Product details
Overview
TPS2836D from Texas Instruments is a noninverting high-side/low-side dual MOSFET driver IC for synchronous-buck power stages, delivering 2.4-A typical peak output current per channel, 50-ns max rise/fall times with 3.3-nF load, and adaptive dead-time control to prevent shoot-through-used in high-current single-phase DC/DC converters powering CPUs, FPGAs, and telecom infrastructure.
For engineers reviewing the TPS2836D datasheet, TPS2836D pinout, TPS2836D application, or TPS2836D equivalent, key selection criteria include TTL-compatible noninverting input logic, bootstrap or ground-reference high-side configuration, −40°C to 125°C junction temperature range, SOIC-8 package compatibility, and integration of internal Schottky bootstrap diode for simplified layout.
Technical Context
The TPS2836D implements adaptive dead-time control by monitoring the BOOTLO node (junction of high-side and low-side FETs) via the DT terminal, dynamically delaying turn-on of either driver to eliminate cross-conduction. Its bipolar-MOSFET parallel output stage enables 2.4-A peak sink/source capability while maintaining low 75-Ω typical output resistance at 12-V drive conditions.
It operates across 4.5-V to 15-V VCC and supports bootstrap voltages up to 30-V (BOOT-to-PGND), with TTL-level input thresholds (VIH = 2 V, VIL = 1 V) and propagation delays as low as 60 ns (HIGHDR low) and 60 ns (LOWDR low) at 12-V supply-optimized for high-frequency (>200 kHz) buck regulators requiring precise timing and robust gate drive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 4.5 V to 15 V - supports wide-input industrial and telecom power rails without external regulation |
| Peak output current | 2.4 A typical (high-side), 3.5 A typical (low-side) - drives large gate capacitances of low-rDS(on) N-channel MOSFETs |
| Rise/fall time | 50 ns max (HIGHDR), 30 ns max (LOWDR) with 3.3-nF load - enables >1 MHz switching in optimized layouts |
| Adaptive dead-time control | Hardware-based DT terminal sensing - eliminates need for external timing components or controller-level dead-time tuning |
| Input logic type | TTL-compatible noninverting - interfaces directly with PWM controllers (e.g., TL5001A) without level-shifting or inversion logic |
| Operating junction temperature | −40°C to 125°C - qualified for under-hood automotive, base station, and industrial embedded power applications |
| Quiescent supply current | 3 mA typical at 12 V, 200 kHz - minimizes no-load power loss in always-on power management systems |
Pinout & Package
TPS2836D is housed in an 8-pin SOIC (D) package per JEDEC MS-012, with gull-wing leads, 1.27-mm pitch, and 3.91-mm body width. Pin 1 is located at the top-left corner (Q1 quadrant) in tape-and-reel packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Digital input | Noninverting TTL-compatible control signal - directly accepts PWM output from controllers like TL5001A |
| PGND (Pin 2) | Power ground | Low-impedance return path for high-current gate drive loops - must be connected to MOSFET source/common power ground |
| DT (Pin 3) | Dead-time sense | Connects to high-side/low-side FET junction - enables adaptive shoot-through prevention without external RC networks |
| VCC (Pin 4) | Supply input | 4.5–15 V main supply - requires local 1-µF ceramic bypass capacitor to PGND for stable high-frequency operation |
| LOWDR (Pin 5) | Low-side driver output | Drives gate of low-side N-MOSFET - capable of 3.5-A sink current to rapidly discharge gate capacitance |
| BOOTLO (Pin 6) | Bootstrap return | Connects to high-side/low-side FET junction - forms return path for bootstrap capacitor and DT sensing |
| HIGHDR (Pin 7) | High-side driver output | Drives gate of high-side N-MOSFET - uses internal Schottky diode to charge bootstrap capacitor during low-side conduction |
| BOOT (Pin 8) | Bootstrap supply | Floats above BOOTLO - develops ~12 V gate drive for high-side FET using external 0.1–1 µF ceramic capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive dead-time control | Eliminates shoot-through without fixed delay circuits or controller firmware intervention - improves efficiency and thermal margin in high-current buck stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-side/low-side MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2837D | Inverting input logic; otherwise identical pinout, specs, and package - requires inverted PWM signal or external inverter | Suitable where controller outputs active-low PWM or system-level logic inversion is already present | Select TPS2837D only if inverting input matches existing controller interface; otherwise TPS2836D avoids added logic complexity |
| LM5109BMAX/NOPB | CMOS input (not TTL), higher 1.5-A peak drive, no integrated bootstrap diode - requires external Schottky diode and level-shifting for TTL sources | Better suited for ultra-low quiescent current (<100 µA) or high-temperature (>125°C) applications where bootstrap diode omission is acceptable | Choose LM5109B only when CMOS compatibility and lower IQ outweigh added BOM cost and layout complexity of external diode |
Compared with TPS2836D, TPS2837D offers identical performance but inverted logic - ideal for matching existing controller polarity, while LM5109BMAX trades integrated bootstrap functionality for lower IQ and CMOS inputs, increasing design effort but extending thermal operating margin.

FAQ
What is the function of the DT pin on the TPS2836D?
The DT (dead-time) pin on the TPS2836D connects to the junction of the high-side and low-side power MOSFETs. It enables hardware-based adaptive dead-time control that prevents shoot-through by ensuring neither driver turns on until the opposing FET's voltage has fully settled. This eliminates reliance on fixed-delay circuits or controller-level timing adjustments, improving efficiency and reliability in high-current buck converters using the TPS2836D.
Does the TPS2836D include an integrated bootstrap diode?
Yes, the TPS2836D integrates a Schottky bootstrap diode between the VCC and BOOT pins. This allows automatic charging of the external bootstrap capacitor (typically 0.1–1 µF) during low-side conduction, eliminating the need for an external diode and reducing component count, board space, and potential failure points in high-reliability power designs using the TPS2836D.
What is the maximum allowable voltage between BOOT and PGND for the TPS2836D?
The absolute maximum voltage between BOOT and PGND for the TPS2836D is 30 V, as specified in the Absolute Maximum Ratings table. This rating supports safe operation during transient overvoltage events such as load dump in automotive applications or input surges in industrial systems, provided the external bootstrap capacitor and associated circuitry are rated accordingly for the TPS2836D.
Can the TPS2836D drive both N-channel MOSFETs in a synchronous buck configuration?
Yes, the TPS2836D is explicitly designed to drive two N-channel MOSFETs in a synchronous-buck topology - the HIGHDR output drives the high-side N-MOSFET gate using bootstrap voltage, and the LOWDR output drives the low-side N-MOSFET gate referenced to PGND. Its 2.4-A peak high-side and 3.5-A peak low-side drive capability ensures fast switching of low-rDS(on) devices, making the TPS2836D ideal for high-efficiency, high-current buck regulators.
What package type and lead finish does the TPS2836D use?
The TPS2836D is supplied in an 8-pin SOIC (D) package per JEDEC MS-012, with gull-wing leads and 1.27-mm pitch. The active tape-and-reel variant TPS2836DR features NiPdAu (NIPDAU) lead finish and meets RoHS requirements, with Moisture Sensitivity Level (MSL) 1 and unlimited peak reflow tolerance at 260°C - ensuring compatibility with standard surface-mount assembly processes for the TPS2836D.
