Product details
Overview
TPS2833D from Texas Instruments is an inverting-input dual MOSFET driver IC for synchronous-buck power stages, delivering 2.4-A peak high-side and low-side output current, supporting 4.5–15-V supply voltage, featuring adaptive dead-time control and internal Schottky bootstrap diode, and optimized for high-current single-phase DC/DC converters.
For engineers reviewing the TPS2833D datasheet, TPS2833D pinout, TPS2833D application, or TPS2833D equivalent, key selection considerations include inverting input logic, SOIC-8 package compatibility, bootstrap vs. ground-referenced high-side configuration, and shoot-through prevention via DT terminal sensing at the power FET junction.
Technical Context
The TPS2833D 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 sink/source into 3.3-nF loads. Its adaptive dead-time circuit monitors the BOOTLO node to dynamically delay turn-on transitions, eliminating shoot-through without fixed timing constraints.
Input logic is inverting - a high IN signal disables HIGHDR and enables LOWDR - enabling direct interface with noninverting PWM controllers like TL5001A. The internal Schottky bootstrap diode reduces external component count and improves charge efficiency during high-frequency operation up to several hundred kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 15 V - supports wide-input industrial and telecom DC/DC supplies without external regulation. |
| Peak Output Current | 2.4 A (high-side and low-side) - drives large-gate-charge N-channel MOSFETs (e.g., Si4410) in high-current buck stages. |
| Rise/Fall Time | ≤50 ns (HIGHDR), ≤30 ns (LOWDR) at VCC = 12 V, CL = 3.3 nF - enables >1-MHz switching with minimal switching loss. |
| Propagation Delay | ≤100 ns (HIGHDR), ≤70 ns (LOWDR) - ensures tight timing alignment between high- and low-side drive signals. |
| Operating Temperature | −40°C to 125°C virtual junction - validated for under-hood automotive and industrial ambient environments. |
| Dead-Time Control | Adaptive DT sensing at BOOTLO - eliminates need for external RC networks and prevents shoot-through across full load range. |
| Bootstrap Diode | Integrated Schottky - reduces external BOM count and improves bootstrap capacitor recharge efficiency at high duty cycles. |
Pinout & Package
TPS2833D is housed in an 8-pin SOIC (D) package with standard 1.27-mm pitch, RoHS-compliant NiPdAu lead finish, and MSL Level-1 rating (260°C reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Digital input control | Inverting logic: high IN disables high-side and enables low-side - matches noninverting PWM controller outputs. |
| PGND (Pin 2) | Power ground reference | Return path for high-current gate drive loops; must be connected directly to MOSFET source/common node. |
| DT (Pin 3) | Dead-time sense input | Connected to BOOTLO (Q1–Q2 junction); enables adaptive delay to prevent simultaneous conduction of power FETs. |
| VCC (Pin 4) | Driver supply input | 4.5–15-V bias rail; requires local 1-µF ceramic bypass to PGND for stable high-frequency operation. |
| LOWDR (Pin 5) | Low-side gate driver output | Ground-referenced output driving N-MOSFET source; capable of 2.4-A sink/source into 3.3-nF load. |
| BOOTLO (Pin 6) | Bootstrap return node | Connects to high-side/low-side MOSFET junction; serves as reference for bootstrap capacitor and DT sensing. |
| HIGHDR (Pin 7) | High-side gate driver output | Floating output referenced to BOOT; drives N-MOSFET gate with 2.4-A peak current and <50-ns rise time. |
| BOOT (Pin 8) | Bootstrap supply input | Accepts up to 30-V bootstrap voltage; internal Schottky diode charges external 0.1–1-µF ceramic capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Inverting input logic | Enables seamless interface with standard noninverting PWM controllers (e.g., TL5001A), eliminating external inverters. |
| Adaptive dead-time control | Monitors BOOTLO voltage to dynamically adjust turn-on delays - eliminates fixed dead-time tuning and shoot-through risk. |
| Integrated Schottky bootstrap diode | Reduces external component count by one diode and improves bootstrap capacitor recharge efficiency at high frequencies. |
| 2.4-A peak drive capability | Supports fast switching of high-Qg MOSFETs (e.g., >20 nC gate charge) in 3-A+ synchronous buck converters. |
| SOIC-8 thermal performance | 600-mW power dissipation at TA ≤ 25°C with 6.0 mW/°C derating - suitable for compact, unheatsinked PCB layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2832D | Noninverting input logic; otherwise identical pinout, specs, and SOIC-8 package. | Requires inverting PWM controller or external inverter; unsuitable where IN polarity must match TL5001A output. | Select TPS2832D only when controller provides inverted gate drive signals or system-level inversion is available. |
| TPS2831 | Adds ENABLE, SYNC, and CROWBAR functions; TTL-compatible inputs; same inverting logic. | Supports multi-phase synchronization and fault shutdown - not needed in simple single-phase buck designs. | Choose TPS2831 only if phase interleaving, enable control, or overcurrent crowbar protection are required. |
Compared with TPS2832D, the TPS2833D's inverting input simplifies interface to common noninverting controllers, while TPS2831 adds complexity and cost for features unnecessary in basic synchronous-buck topologies - making TPS2833D the optimal balance of integration, compatibility, and minimal BOM.

FAQ
What is the logic polarity of the TPS2833D input?
The TPS2833D features an inverting input: a logic-high signal on the IN pin disables the high-side driver (HIGHDR) and enables the low-side driver (LOWDR). This allows direct interfacing with noninverting PWM controllers such as the TL5001A without external inverters. The TPS2833D datasheet confirms this behavior in the "IN" section of the detailed description and functional block diagram.
Does the TPS2833D require an external bootstrap diode?
No, the TPS2833D integrates a Schottky bootstrap diode internally, connecting VCC to the BOOT terminal. This eliminates the need for an external diode in typical bootstrap configurations, reducing BOM count and improving charge efficiency - a key differentiator from earlier discrete-driver solutions. The datasheet explicitly states "Internal Schottky Bootstrap Diode" in the feature list and pin description for BOOT.
What is the maximum allowable voltage between BOOT and PGND on the TPS2833D?
The absolute maximum voltage between BOOT and PGND is 30 V, as specified in the Absolute Maximum Ratings table. This rating enables use with high-input-voltage buck stages (e.g., 24-V input) when paired with appropriately rated MOSFETs and bootstrap capacitors. Exceeding 30 V risks permanent damage, and the recommended operating range is up to 28 V per the "Input voltage: BOOT to PGND" row in Recommended Operating Conditions.
How does the adaptive dead-time control work on the TPS2833D?
The TPS2833D implements adaptive dead-time control by monitoring the BOOTLO terminal - the junction of the high-side and low-side power MOSFETs. When BOOTLO voltage falls below a threshold, the driver delays high-side turn-on; when it rises, it delays low-side turn-on. This dynamic sensing prevents shoot-through across the full operating range without fixed RC timing components, as confirmed in the "dead-time (DT) control" subsection of the detailed description.
Is the TPS2833D pin-compatible with other devices in the TPS283x family?
Yes, all TPS283x devices - including TPS2832D, TPS2833D, TPS2831, and TPS2835 - share identical SOIC-8 (D) pinouts and terminal functions. Differences lie solely in input logic (inverting/noninverting), added features (ENABLE/SYNC/CROWBAR), and input compatibility (CMOS/TTL). The D-package mechanical drawing and Terminal Functions table confirm consistent pin numbering and roles across the family.
