Product details
Overview
TPS2839PWP from Texas Instruments is an inverting dual-channel MOSFET driver IC designed for synchronous-buck power supplies, delivering 4-A peak source/sink current per channel at VDRV up to 14 V, featuring adjustable drive regulator (4–14 V), adaptive dead-time control, and integrated Schottky bootstrap diode - used in high-current DC/DC modules requiring precise gate timing and shoot-through protection.
For engineers reviewing the TPS2839PWP datasheet, TPS2839PWP pinout, TPS2839PWP application, or TPS2839PWP equivalent, key selection considerations include its inverting logic configuration, 16-pin HTSSOP PowerPAD package with thermal pad, adjustable VDRV regulation via external resistors, TTL-compatible digital inputs, and synchronous/nonsynchronous mode control via SYNC pin.
Technical Context
The TPS2839PWP implements a dual-driver architecture with independent high-side (bootstrap-referenced) and low-side (ground-referenced) outputs, each capable of 4-A peak current. Its integrated 150-mA adjustable regulator sets VDRV between 4 V and 14 V using external R1/R2 feedback, enabling optimization for specific N-channel MOSFET gate thresholds.
Dead-time management combines fixed nonoverlap (30–150 ns) with adaptive turn-on delay controlled by the DELAY capacitor and DT pin sensing BOOTLO voltage collapse, preventing shoot-through during high-frequency switching. The inverting input logic means HIGHDR goes low when IN goes high - critical for controller interface compatibility in synchronous buck topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRV range | Adjustable 4 V to 14 V output - enables gate drive voltage tuning for optimal RDS(on) vs. switching loss trade-off in N-MOSFETs. |
| Peak output current | 4 A source/sink per channel - supports fast charging/discharging of ≥3.3 nF gate loads with ≤65 ns rise/fall times at 14 V. |
| Supply voltage (VCC) | 10 V to 15 V - requires minimum 2 V headroom above VDRV; includes UVLO with 10.3 V start/7.5 V stop threshold. |
| Dead-time control | Adjustable via DELAY capacitor + adaptive DT sensing - ensures safe turn-on sequencing and prevents cross-conduction in half-bridge configurations. |
| Logic type | Inverting - HIGHDR output is inverted relative to IN input, matching controllers requiring active-low high-side drive signals. |
| Package | 16-pin HTSSOP (PWP) with exposed thermal pad - delivers 2.07 °C/W junction-to-case thermal resistance when soldered to PCB copper. |
| PWRRDY function | Open-drain status indicator - asserts low only when both VCC ≥10.3 V and VDRV regulator is stable, enabling safe controller enable sequencing. |
Pinout & Package
TPS2839PWP uses a thermally enhanced 16-pin HTSSOP PowerPAD (PWP) package (5.1 mm × 6.6 mm), with an exposed leadframe thermal pad on the bottom surface soldered to PCB ground plane for optimal heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENABLE (Pin 1) | Digital enable input | TTL-compatible active-high signal; drives both outputs low when disabled - essential for system-level power sequencing and fault shutdown. |
| IN (Pin 2) | Control input | Inverting logic input: HIGH on IN forces LOWDR high and HIGHDR low - defines fundamental phase relationship for synchronous rectification. |
| PWRRDY (Pin 3) | Power-good status | Open-drain output indicating valid VCC and stable VDRV - used to gate controller PWM enable or microcontroller reset release. |
| DELAY (Pin 4) | Dead-time adjustment | Capacitor-connected node setting high-side turn-on delay after low-side turn-off - compensates for gate resistor-induced timing skew. |
| SYNC (Pin 5) | Synchronous mode control | TTL-compatible input: HIGH enables low-side FET as synchronous rectifier; LOW disables it for nonsynchronous (diode-rectified) operation. |
| ADJ (Pin 6) | Regulator feedback | Resistor-divider node for VDRV setpoint - connects to R1/R2 network to program 4–14 V output per VDRV = 1.235×(1+R2/R1). |
| DT (Pin 7) | Dead-time sense | Connects to BOOTLO node - monitors high/low-FET junction voltage to trigger adaptive dead-time extension until BOOTLO falls below threshold. |
| AGND (Pin 8) | Analog reference ground | Separate ground return for internal references and regulators - must be tied to PGND at single point to avoid noise coupling into VDRV control loop. |
| BOOT (Pin 16) | Bootstrap supply | Connects to bootstrap capacitor top plate - develops floating high-side gate drive voltage; rated for 30 V max relative to PGND. |
| HIGHDR (Pin 15) | High-side gate driver | Output driving bootstrap-referenced N-MOSFET gate - sourced/sunk 4-A peak with <100 ns propagation delay at 14 V VDRV. |
| BOOTLO (Pin 14) | Bootstrap return | Connects to high/low-FET source/drain junction - provides return path for bootstrap capacitor and DT sense node. |
| VDRV (Pin 12) | Drive regulator output | Programmable gate drive rail - powers both driver channels; bypassed with ≥1 µF ceramic capacitor to PGND for stability. |
| LOWDR (Pin 11) | Low-side gate driver | Ground-referenced output driving N-MOSFET gate - achieves 40 ns propagation delay and 3.3 nF load in 10 ns rise/fall at room temperature. |
| PGND (Pin 9) | Power ground | Main return path for high-current driver outputs and bootstrap capacitor discharge - must be low-inductance connection to minimize ground bounce. |
| VCC (Pin 13) | Main supply input | 10–15 V input powering internal logic and regulator - requires ≥1 µF ceramic bypass capacitor directly to PGND near pin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2838PWP | Noninverting logic; identical pinout, package, and VDRV adjustability - differs only in IN-to-HIGHDR polarity. | Requires controller with active-high high-side drive signal; unsuitable where inverting logic is mandated by system architecture. | Select when controller interface demands noninverted gate drive and layout reuse of TPS2839PWP footprint is acceptable. |
| TPS28225DR | Single-channel, 4-A inverting driver in 8-pin SOIC; no VDRV regulator or SYNC pin - relies on external gate drive rail. | Lacks integrated dead-time control and bootstrap diode; requires external components for synchronous operation and higher BOM cost. | Choose for space-constrained designs where only one side needs driving or where external VDRV generation is already present. |
Compared with TPS2838PWP, the TPS2839PWP provides inverting logic essential for certain controller interfaces, while TPS28225DR offers smaller footprint but sacrifices integration - making TPS2839PWP optimal for thermally demanding, highly integrated synchronous-buck designs requiring precise dead-time and regulated gate drive.

FAQ
What is the logic configuration of the TPS2839PWP?
The TPS2839PWP features inverting logic: when the IN pin is driven high, the HIGHDR output goes low and LOWDR goes high. This matches controllers like TL5001ACD that require active-low high-side drive signals. The TPS2839PWP datasheet confirms this behavior on page 5 under "IN" description, distinguishing it from the noninverting TPS2838PWP variant.
How is the VDRV output voltage adjusted on the TPS2839PWP?
The TPS2839PWP uses the ADJ pin (Pin 6) with an external resistor divider (R1 to AGND, R2 between ADJ and VDRV) to set VDRV from 4 V to 14 V using the formula VDRV = 1.235 × (1 + R2/R1). For example, R1 = 30 kΩ and R2 = 165 kΩ yields 12 V. This adjustment is exclusive to TPS2839PWP and TPS2838PWP - not available on TPS2849/TPS2848.
Does the TPS2839PWP include an integrated bootstrap diode?
Yes, the TPS2839PWP integrates a Schottky diode between BOOT and VDRV pins, eliminating the need for an external bootstrap diode in typical synchronous-buck configurations. This reduces component count, PCB area, and forward voltage drop during bootstrap capacitor recharge - a feature explicitly listed in the "FEATURES" section of the TPS2839PWP datasheet.
What is the purpose of the SYNC pin on the TPS2839PWP?
The SYNC pin (Pin 5) controls synchronous versus nonsynchronous operation: when SYNC is high, the low-side driver operates as a synchronous rectifier; when low, the low-side driver is disabled, forcing diode-based rectification. This enables flexible topology selection without hardware changes - a capability confirmed in the "SYNC (TPS283x only)" section on page 5 of the TPS2839PWP datasheet.
What thermal performance can be expected from the TPS2839PWP package?
The TPS2839PWP uses a 16-pin HTSSOP PowerPAD (PWP) package with an exposed thermal pad. When soldered to a PCB with adequate copper area and thermal vias, it achieves a junction-to-case thermal resistance of 2.07 °C/W. The Dissipation Rating Table shows 2739 mW at TA ≤25°C with soldered pad - enabling sustained 4-A peak currents at 125°C junction temperature in properly designed layouts.
