Product details
Overview
TPS2839PWPRG4 from Texas Instruments is an inverting dual MOSFET gate driver IC for synchronous-buck power stages, delivering 4-A peak source/sink current per channel at VDRV up to 14 V, featuring adjustable drive-regulator output (4–14 V), adaptive dead-time control, and integrated Schottky bootstrap diode - used in high-current DC/DC modules and multiphase VRMs.
For engineers reviewing the TPS2839PWPRG4 datasheet, TPS2839PWPRG4 pinout, TPS2839PWPRG4 application, or TPS2839PWPRG4 equivalent, key selection criteria include inverting logic compatibility, 16-pin HTSSOP PowerPAD thermal performance, VDRV adjustability via external resistors, and shoot-through protection with DT/DELAY-configurable dead time.
Technical Context
The TPS2839PWPRG4 implements a dual-channel, inverting gate driver architecture with independent high-side (bootstrap-referenced) and low-side (ground-referenced) outputs. Its integrated 150-mA adjustable regulator sets VDRV from 4 V to 14 V using R1/R2 feedback on the ADJ pin, enabling optimization for specific N-channel MOSFET gate thresholds and rDS(on).
Dead-time control combines fixed nonoverlap timing (30–150 ns) with adaptive turn-on delay: HIGHDR activation is gated by BOOTLO voltage decay below threshold, while DELAY pin capacitor tuning adds programmable high-side turnon delay (0.5–1.5 ns/pF). The device supports synchronous/nonsynchronous operation via TTL-compatible SYNC input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Drive Output Current | 4-A peak source/sink per channel - drives 3.3-nF loads with ≤65-ns rise/fall times at 14-V VDRV, enabling fast switching of low-rDS(on) power MOSFETs. |
| VDRV Range | Adjustable 4 V to 14 V - set via external R1/R2 on ADJ pin; allows matching gate-drive voltage to MOSFET threshold and conduction loss trade-offs. |
| Supply Voltage (VCC) | 10 V to 15 V - requires ≥2 V headroom above VDRV; powers internal logic and regulator; includes UVLO with 10.3-V start/7.5-V stop threshold. |
| Dead-Time Control | Adaptive + adjustable: BOOTLO-sensed turnon blocking plus DELAY pin capacitor (0–50 pF) for 0.5–1.5 ns/pF fine-tuning - prevents shoot-through in hard-switching buck topologies. |
| Logic Polarity | Inverting - high IN yields low HIGHDR; matches controllers requiring inverted PWM signals for high-side FET control in synchronous rectification. |
| Package Thermal Performance | 16-pin HTSSOP (PWP) with exposed PowerPAD - achieves 2.07 °C/W junction-to-case thermal resistance when soldered, supporting >10-W dissipation at TA = 70°C. |
| PWRRDY Function | Open-drain status indicator - asserts low only when both VCC ≥10.3 V and VDRV regulator output is stable, enabling safe controller enable sequencing. |
Pinout & Package
TPS2839PWPRG4 uses the 16-pin HTSSOP (PWP) package with exposed thermal pad (5.1 mm × 6.6 mm), optimized for PCB heat sinking via soldered PowerPAD. Pin numbering follows standard top-view orientation with pin 1 at bottom-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENABLE (1) | Global driver enable | TTL-compatible active-high input; forces both HIGHDR and LOWDR low when disabled - ensures safe power-stage shutdown. |
| IN (2) | Inverting control input | Accepts PWM signal; high IN produces low HIGHDR and high LOWDR - matches inverted gate-drive requirements of synchronous buck controllers. |
| PWRRDY (3) | Power-good status | Open-drain output indicating VCC ≥10.3 V and stable VDRV - used to enable downstream controller after power rail stabilization. |
| DELAY (4) | High-side turnon delay | Connects to capacitor-to-ground to add programmable delay before HIGHDR activation - compensates for gate-resistor-induced turnoff lag. |
| SYNC (5) | Synchronous mode control | TTL input: high enables low-side FET as synchronous rectifier; low disables LOWDR - allows nonsynchronous operation for light-load efficiency. |
| ADJ (6) | VDRV feedback node | Connects to resistor divider (R1/R2) between VDRV and PGND - sets regulated VDRV output per VDRV = 1.235×(1+R2/R1). |
| DT (7) | Dead-time sensing | Connects to phase node (Q1/Q2 junction); monitors BOOTLO voltage to enforce adaptive dead time - blocks HIGHDR until BOOTLO falls below threshold. |
| AGND (8) | Analog ground reference | Separate ground for internal references and regulators - must be tied to PGND at single point to minimize noise coupling into VDRV regulation. |
| BOOT (16) | Bootstrap supply input | Connects to bootstrap capacitor (0.1–1 µF) between BOOT and BOOTLO - supplies floating gate-drive voltage for high-side N-MOSFET. |
| HIGHDR (15) | High-side gate driver output | Drives gate of high-side N-MOSFET referenced to BOOT/BOOTLO - capable of 4-A peak current with <4-Ω sink resistance at 14-V VDRV. |
| BOOTLO (14) | Bootstrap return / phase node | Connects to source of high-side FET and drain of low-side FET - serves as bootstrap capacitor return and DT-sensing point for adaptive dead time. |
| VDRV (12) | Regulated gate-drive supply | Output of internal adjustable regulator (4–14 V); powers both driver channels - decoupled with ≥1-µF ceramic capacitor to PGND. |
| LOWDR (11) | Low-side gate driver output | Ground-referenced output driving low-side N-MOSFET gate - delivers 4-A peak current with <7-Ω sink resistance and 30-ns propagation delay at 125°C. |
| PGND (9) | Power ground return | Main return path for driver output currents and VDRV/VCC decoupling - must be low-inductance connection to PCB ground plane. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2838PWPR | Noninverting logic; identical pinout, VDRV adjustability, and thermal specs - differs only in IN→HIGHDR polarity. | Requires controller with noninverted PWM output; unsuitable where inverting logic is mandated by system architecture. | Select TPS2838PWPR only if controller interface demands noninverting behavior; otherwise TPS2839PWPRG4 maintains correct signal polarity. |
| LM5113SDX/NOPB | Fixed 10-V VDD output; no ADJ pin; higher 5-A peak current; separate high/low VDD supplies; no integrated bootstrap diode. | Needs external bootstrap diode and dual supply routing; better suited for ultra-high-current (>5 A) or multi-rail gate-drive architectures. | Choose LM5113SDX/NOPB for designs requiring >4-A drive or split-supply flexibility; TPS2839PWPRG4 preferred for compact, integrated bootstrap solutions. |
Compared with TPS2838PWPR, TPS2839PWPRG4 provides inverting logic essential for certain controller interfaces, while LM5113SDX/NOPB offers higher current but sacrifices integration - making TPS2839PWPRG4 optimal for thermally constrained, cost-sensitive synchronous-buck designs needing adjustable VDRV and embedded bootstrap diode.

FAQ
What is the logic polarity of the TPS2839PWPRG4?
The TPS2839PWPRG4 features inverting logic: a high-level signal on the IN pin results in a low-level output on HIGHDR and a high-level output on LOWDR. This matches controllers that require inverted PWM signals for high-side FET control in synchronous-buck topologies. The TPS2838 variant provides noninverting logic for alternative controller interfaces.
How is the VDRV output voltage adjusted on the TPS2839PWPRG4?
The TPS2839PWPRG4 uses the ADJ pin (pin 6) to set VDRV via an external resistor divider between VDRV and PGND. The formula is VDRV = 1.235 V × (1 + R2/R1), allowing adjustment from 4 V to 14 V. Common values include R1 = 30 kΩ and R2 = 165 kΩ for 12-V VDRV, as confirmed in the datasheet's application table.
Does the TPS2839PWPRG4 include an integrated bootstrap diode?
Yes, the TPS2839PWPRG4 integrates a Schottky bootstrap diode internally, eliminating the need for an external diode in the bootstrap circuit. This reduces component count, PCB area, and potential failure points while improving charge-pump efficiency - a key differentiator versus drivers like the LM5113 that require external diodes.
What thermal performance does the TPS2839PWPRG4 deliver in its PWP package?
The TPS2839PWPRG4 in the 16-pin HTSSOP (PWP) package achieves a junction-to-case thermal resistance of 2.07 °C/W when the exposed PowerPAD is soldered to the PCB. At 70°C ambient, it supports up to 1506 mW continuous power dissipation with proper board layout - enabling high-current operation without additional heatsinking.
How does the TPS2839PWPRG4 implement dead-time control?
The TPS2839PWPRG4 uses dual dead-time mechanisms: adaptive control (via DT pin monitoring BOOTLO voltage to block HIGHDR until phase node falls) and adjustable delay (via capacitor on DELAY pin adding 0.5–1.5 ns/pF). This prevents shoot-through across varying MOSFET gate resistances and layout parasitics in high-frequency buck converters.
