Product details
Overview
TPS2832D from Texas Instruments is a noninverting high-side/low-side dual MOSFET driver IC for synchronous-buck power stages, delivering 2.4-A peak source/sink current per output, operating from 4.5-V to 15-V supply, with adaptive dead-time control and internal Schottky bootstrap diode. It targets high-current single-phase DC-DC converters in telecom and industrial power supplies.
For engineers reviewing the TPS2832D datasheet, TPS2832D pinout, TPS2832D application, or TPS2832D equivalent, key selection criteria include bootstrap-configurable high-side drive, 50-ns max rise/fall time into 3.3-nF load, −40°C to 125°C junction temperature range, SOIC-8 package compatibility, and noninverting input logic polarity.
Technical Context
The TPS2832D integrates two independent gate drivers: a floating bootstrap high-side driver (capable of 30-V BOOT-to-PGND) and a ground-referenced low-side driver, both rated for 2.4-A peak output. Its adaptive dead-time circuit connects to the power FET junction via DT pin to prevent shoot-through by enforcing turn-off-before-turn-on sequencing.
Input logic is CMOS-compatible with 0.7×VCC high-level threshold; the noninverting IN terminal directly controls both outputs. Internal Schottky diode enables efficient bootstrap capacitor charging without external diode, reducing BOM count and layout complexity in high-frequency buck regulators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 4.5 V to 15 V - supports wide-input industrial and telecom rails without external regulation |
| Peak output current | 2.4 A typical - drives large gate capacitance of low-Rds(on) N-channel MOSFETs at high switching frequencies |
| Rise/fall time | 50 ns max (3.3-nF load) - enables >1-MHz operation with minimal switching loss |
| Propagation delay | 100 ns max (excluding dead time) - ensures tight timing control in fast transient response designs |
| Operating temperature | −40°C to 125°C virtual junction - qualified for under-hood and industrial ambient environments |
| Quiescent current | 3 mA typical - minimizes no-load power loss in always-on systems |
| Bootstrap voltage limit | 30 V max (BOOT to PGND) - accommodates high-voltage buck stages up to 24-V input |
Pinout & Package
TPS2832D is housed in an 8-pin SOIC (D) package with exposed pad not present; footprint matches JEDEC MS-012AC standard. Pin 1 (IN) is located at top-left corner when notch faces upward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Digital input | Noninverting control signal - high = HIGHDR on / LOWDR on; logic thresholds scale with VCC |
| PGND (Pin 2) | Power ground | Return path for low-side driver and bootstrap discharge - must connect to FET source node |
| DT (Pin 3) | Analog sensing input | Dead-time feedback node - connected to high/low FET junction to dynamically adjust overlap guardband |
| VCC (Pin 4) | Supply input | Main bias rail - requires local 1-µF ceramic decoupling to PGND for stable gate drive |
| LOWDR (Pin 5) | Low-side output | Ground-referenced gate driver - sinks/sources up to 2.4 A to drive N-channel MOSFET source |
| BOOTLO (Pin 6) | Bootstrap return | Connects to high/low FET junction - forms floating reference for high-side driver during bootstrapping |
| HIGHDR (Pin 7) | High-side output | Floating gate driver - sources up to 2.4 A to drive N-channel MOSFET gate above input rail |
| BOOT (Pin 8) | Bootstrap supply | Charged via internal Schottky diode - holds ~VCC above BOOTLO to enable high-side conduction |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive dead-time control | Eliminates need for fixed external RC timing; prevents shoot-through across full load and temperature range |
| Integrated Schottky bootstrap diode | Reduces component count and PCB area vs discrete diode solutions; improves bootstrap efficiency at high duty cycles |

| 50-ns max rise/fall into 3.3-nF | Enables clean edge integrity with minimal ringing in high-dV/dt buck topologies |
| −40°C to 125°C junction rating | Validated for continuous operation in sealed enclosures or high-ambient industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2833D | Inverting input logic; otherwise identical pinout, specs, and SOIC-8 package | Requires inverted PWM signal or upstream inverter; same dead-time, drive strength, and thermal performance | Select when system controller outputs active-low gate signals or inverting logic simplifies timing alignment |
| UCC27201D | Higher 4-A peak current, 12-V max VCC, no integrated bootstrap diode, 105°C max TJ | Requires external bootstrap diode; better suited for higher-current, lower-temperature applications | Choose for >3-A gate drive needs where external diode integration is acceptable and 125°C operation not required |
Compared with TPS2832D, TPS2833D offers identical performance with inverted logic polarity-ideal for direct substitution where signal inversion is acceptable-while UCC27201D trades integrated bootstrap diode and extended temperature for higher peak current, making it suitable for higher-power but thermally less demanding designs.

FAQ
What is the input logic polarity of the TPS2832D?
The TPS2832D features a noninverting input: a high-level signal on the IN pin (Pin 1) simultaneously enables the HIGHDR output and disables the LOWDR output. This matches controllers that output active-high PWM signals without requiring external inversion. The TPS2832D input threshold is 0.7×VCC, ensuring compatibility across its 4.5-V to 15-V supply range.
Does the TPS2832D require an external bootstrap diode?
No, the TPS2832D integrates a Schottky bootstrap diode internally between VCC and BOOT pins. This eliminates the need for an external diode, reduces PCB area, and improves bootstrap efficiency-especially at high duty cycles-while maintaining full 30-V BOOT-to-PGND rating. External diode addition is unnecessary and may impair performance.
What is the maximum allowable voltage between BOOT and PGND on the TPS2832D?
The absolute maximum voltage between BOOT and PGND for the TPS2832D is 30 V. This rating allows safe operation in buck converters with input voltages up to 24 V, accounting for overshoot and ringing. Exceeding 30 V risks permanent damage; design margins should keep BOOT–PGND ≤28 V under worst-case transient conditions.
How does the adaptive dead-time control function in the TPS2832D?
The TPS2832D's adaptive dead-time control monitors the voltage at the DT pin (connected to the high/low FET junction). It delays high-side turn-on until the low-side FET is fully off and delays low-side turn-on until the drain voltage falls below threshold-dynamically preventing shoot-through across all load, temperature, and layout variations without fixed RC tuning.
Is the TPS2832D pin-compatible with other devices in the TPS283x family?
Yes, the TPS2832D shares identical SOIC-8 pinout and electrical specifications with TPS2833D (inverting version), TPS2832DR (tape-and-reel variant), and TPS2833D. All share the same terminal functions, thermal ratings, and drive capabilities-only the input logic polarity differs between TPS2832D and TPS2833D, enabling drop-in replacement where signal polarity aligns.
