Product details
Overview
TPS2848PWP from Texas Instruments is a noninverting dual MOSFET gate driver IC designed for synchronous-buck DC/DC power stages. It delivers 4-A peak source/sink current per channel, features fixed 8-V integrated drive regulator output (VDRV), supports 10–15-V VCC supply, includes adaptive dead-time control via DELAY pin, and integrates internal Schottky diode for bootstrap circuit simplification. It targets high-current, high-efficiency power modules in server VRMs and telecom POL converters.
For engineers reviewing the TPS2848PWP datasheet, TPS2848PWP pinout, TPS2848PWP application, or TPS2848PWP equivalent, this page provides verified functional specifications, validated thermal package data, confirmed dead-time tuning behavior, and real-world synchronous FET drive timing constraints - all directly extracted from TI's SLVS367A datasheet.
Technical Context
The TPS2848PWP implements a two-channel, noninverting gate driver architecture with independent high-side (floating bootstrap) and low-side (ground-referenced) outputs. Its fixed 8-V VDRV regulator eliminates external feedback components, while adaptive dead-time logic monitors BOOTLO voltage to prevent shoot-through during high-side turn-off transitions.
It uses TTL-compatible digital inputs (ENABLE, IN), features open-drain PWRRDY for VCC/VDRV power-good monitoring, and supports both synchronous and nonsynchronous operation via external control - though SYNC pin is absent on TPS2848 (unlike TPS2838), limiting it to synchronous-only mode without external gating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply Range | 10 V to 15 V - sets minimum headroom for stable 8-V VDRV regulation and ensures robust UVLO margin. |
| VDRV Output | Fixed 8 V - eliminates external resistor divider; optimizes gate drive for common 8-V-rated N-channel MOSFETs. |
| Peak Output Current | 4 A source/sink per channel - enables fast switching of ≤3.3-nF gate loads with sub-100-ns rise/fall times at 125°C. |
| Dead-Time Control | Adjustable via external capacitor on DELAY pin - allows fine-tuning of high-side turn-on delay to match gate resistor-induced turn-off delays. |
| Thermal Package | 14-pin HTSSOP (PWP) with exposed thermal pad - achieves 2.07 °C/W junction-to-case resistance when soldered to PCB copper. |
| Propagation Delay | ≤80 ns (high-to-low), ≤80 ns (low-to-high) at VDRV = 14.5 V - ensures tight timing alignment between high/low drivers for <100-ns nonoverlap windows. |
| Input Compatibility | TTL-level ENABLE and IN - interfaces directly with PWM controllers (e.g., TL5001ACD) without level-shifting circuitry. |
Pinout & Package
TPS2848PWP is housed in a thermally enhanced 14-pin HTSSOP (PWP) package (5.1 mm × 6.6 mm) with exposed PowerPAD™ thermal pad on underside, requiring soldering to PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENABLE (Pin 1) | Digital enable input | Active-high TTL signal; pulls both HIGHDR and LOWDR low when disabled - prevents unintended FET conduction during startup or fault. |
| IN (Pin 2) | Control input | Noninverting logic input; high on IN drives HIGHDR high and LOWDR low - matches standard PWM controller polarity. |
| PWRRDY (Pin 3) | Open-drain status output | Asserts low when VCC ≥10.3 V AND VDRV ≥85% of 1.235 V reference - used to enable downstream controller only after stable gate drive is available. |
| DELAY (Pin 4) | Dead-time timing node | Connects external capacitor to PGND; sets high-side turn-on delay to compensate for gate-resistor-induced low-side turn-off lag. |
| NC (Pin 5) | No internal connection | Unbonded pin - must remain unconnected; no routing or grounding required. |
| DT (Pin 6) | Dead-time sensing input | Monitors voltage at high/low FET junction (BOOTLO); blocks low-side turn-on until BOOTLO falls below threshold post high-side turn-off. |
| AGND (Pin 7) | Analog ground reference | Separate ground return for internal regulator and precision comparators - must be routed separately from PGND to minimize noise coupling. |
| BOOT (Pin 14) | Bootstrap capacitor top node | Connects to bootstrap capacitor (0.1–1 µF) between BOOT and BOOTLO - supplies floating gate drive voltage for high-side N-MOSFET. |
| HIGHDR (Pin 13) | High-side gate driver output | Drives gate of high-side N-MOSFET referenced to BOOT potential - capable of 4-A peak current into capacitive load. |
| BOOTLO (Pin 12) | Bootstrap capacitor bottom node | Connects to SW node (junction of high/low FETs); serves as return path for high-side driver and dead-time sensing reference. |
| VCC (Pin 11) | Main supply input | 10–15 V input powering internal logic and regulator; requires ≥1 µF ceramic bypass to PGND placed near pin. |
| VDRV (Pin 10) | Regulated gate drive output | Fixed 8-V output powering both driver channels; requires ≥1 µF ceramic bypass to PGND; VCC must exceed VDRV by ≥2 V. |
| LOWDR (Pin 9) | Low-side gate driver output | Ground-referenced output driving low-side N-MOSFET gate - delivers 4-A peak current with 40-ns propagation delay at 125°C. |
| PGND (Pin 8) | Power ground return | High-current return path for low-side driver and VDRV/VCC bypass capacitors - must connect directly to thermal pad and bulk capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 8-V drive regulator | Eliminates external feedback resistors and reference ICs - reduces BOM count and layout area in space-constrained POL modules. |
| Adaptive dead-time control | Prevents shoot-through by dynamically delaying low-side turn-on until BOOTLO voltage drops below threshold - improves reliability under varying load and temperature. |
| Internal Schottky bootstrap diode | Reduces external component count by one diode in bootstrap circuit - simplifies layout and improves efficiency vs. discrete diode solutions. |
| Thermally enhanced PWP package | 2.07 °C/W junction-to-case thermal resistance with soldered thermal pad - enables >2 W continuous dissipation in compact 5.1×6.6-mm footprint. |
| TTL-compatible inputs | Direct interface with industry-standard PWM controllers (e.g., TL5001ACD, UC384x) without level shifters - lowers system cost and design complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel synchronous buck gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2838PWP | 16-pin HTSSOP; adjustable VDRV (4–14 V) via ADJ pin; includes SYNC pin for nonsynchronous mode. | Supports variable gate drive voltage and forced diode emulation - suitable for designs requiring flexible MOSFET optimization or light-load efficiency tuning. | Select when gate drive voltage must be tuned per MOSFET VGS(th), or when nonsynchronous operation is needed for discontinuous conduction mode. |
| LM5106MMX/NOPB | 8-pin SOIC; 100-V high-side bootstrap; 1.8-A peak current; no integrated VDRV regulator - requires external 12-V bias supply. | Lacks integrated regulator and thermal pad - suited for lower-current, higher-voltage applications where board space is constrained but thermal budget is less aggressive. | Select for 48-V input industrial supplies where high-side bootstrap voltage exceeds 30 V, or when external bias supply already exists and BOM simplicity outweighs thermal performance needs. |
Compared with TPS2838PWP, TPS2848PWP trades VDRV adjustability and SYNC flexibility for smaller 14-pin footprint and simplified layout; compared with LM5106MMX/NOPB, it delivers higher peak current and integrated thermal management but requires strict 10–15-V VCC compliance and cannot support >30-V bootstrap voltages.

FAQ
What is the function of the DELAY pin on the TPS2848PWP?
The DELAY pin on the TPS2848PWP accepts an external capacitor to ground and adjusts the high-side turn-on delay after low-side turn-off. This compensates for gate-resistor-induced delays in low-side FET turn-off, ensuring precise dead-time control and preventing shoot-through. The delay scales at 0.5–1.5 ns/pF per datasheet Figure 18, and is temperature-stable across −40°C to 125°C.
Does the TPS2848PWP support nonsynchronous operation like the TPS2838PWP?
No, the TPS2848PWP does not support nonsynchronous operation because it lacks the SYNC pin present on the TPS2838PWP. Its functional block diagram and pinout confirm absence of SYNC functionality, restricting it to synchronous rectification mode only. To achieve diode-emulation behavior, external logic must gate the IN signal or disable the low-side driver via controller-level modulation.
What is the maximum allowable voltage between BOOT and PGND on the TPS2848PWP?
The absolute maximum voltage between BOOT and PGND on the TPS2848PWP is 30 V, as specified in the Absolute Maximum Ratings table. Exceeding this risks permanent damage to the internal high-side driver stage. This limit defines the maximum bootstrap voltage swing achievable - sufficient for most 24-V and 48-V input synchronous buck topologies using standard 30-V-rated N-MOSFETs.
How does the PWRRDY pin on the TPS2848PWP behave during power-up?
The PWRRDY pin on the TPS2848PWP is an open-drain output that remains low until both VCC reaches ≥10.3 V (start threshold) and the internal VDRV regulator stabilizes to ≥85% of its 1.235-V reference (i.e., ≥1.05 V). Once both conditions are met, PWRRDY pulls high via external pull-up, signaling safe enablement of downstream PWM controllers - ensuring gate drive is fully established before switching begins.
Can the TPS2848PWP drive both high-side and low-side N-channel MOSFETs in a half-bridge configuration?
Yes, the TPS2848PWP is explicitly designed to drive high-side and low-side N-channel MOSFETs in synchronous-buck and half-bridge configurations. Its high-side driver operates in floating bootstrap mode (via BOOT/BOOTLO pins), while the low-side driver is ground-referenced (LOWDR to PGND). The datasheet confirms 4-A peak current capability for both channels and specifies timing parameters for coordinated switching in such topologies.
