Product details
Overview
TPS2829DBVT from Texas Instruments is a noninverting single-channel high-speed MOSFET driver in 5-pin SOT-23 (DBV) package, delivering 2-A peak output current with 25-ns max rise/fall times and 40-ns max propagation delay into 1-nF load. It operates from 4-V to 14-V supply, draws ≤15-µA quiescent current when inputs are static, and targets gate-driving in DC/DC converters and motor control stages.
For engineers reviewing the TPS2829DBVT datasheet, TPS2829DBVT pinout, TPS2829DBVT application, or TPS2829DBVT equivalent, key selection criteria include its regulator-free architecture (enabling ultra-low ICC), noninverting logic polarity, BiCMOS output stage for rail-to-rail drive, and operation across –40°C to 125°C ambient range.
Technical Context
The TPS2829DBVT uses a BiCMOS output stage to achieve fast switching with minimal shoot-through current, leveraging CMOS input thresholds at ~2/3 VCC (positive-going) and ~1/3 VCC (negative-going). Its input stage lacks active pullup and internal voltage regulator-distinguishing it from TPS2817/TPS2819-and relies solely on external VCC for both logic and power delivery.
This design eliminates regulator overhead and reduces quiescent current to <15 µA, making it suitable for low-power, high-frequency gate driving where supply headroom is limited to 4–14 V and no auxiliary regulated rail is needed. The device inherently minimizes cross-conduction during transitions via optimized predrive timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output configuration | Noninverting driver: OUT follows IN logic state without inversion |
| Peak output current | 2 A - sufficient to rapidly charge/discharge large MOSFET gate capacitances (e.g., >1 nF) |
| Rise/fall time (max) | 25 ns - enables reliable operation in >1-MHz switching converters |
| Propagation delay (max) | 40 ns - ensures tight timing control between PWM input and MOSFET gate transition |
| Supply voltage range | 4 V to 14 V - compatible with standard 5-V and 12-V logic/system rails, no regulator required |
| Quiescent current (ICC) | ≤15 µA - supports always-on or low-duty-cycle systems without significant standby loss |
| Operating temperature | –40°C to 125°C - qualified for industrial and automotive under-hood environments |
Pinout & Package
TPS2829DBVT is housed in a 5-pin SOT-23 (DBV) surface-mount package, tape-and-reel packaged (250 units per reel), with RoHS-compliant NiPdAu lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Regulator supply input | No internal connection - pin left unconnected (NC) as TPS2829 omits internal regulator |
| 2 - GND | Ground reference | Common return path for input logic, output stage, and supply current |
| 3 - IN | Logic input | CMOS-compatible input accepting 0 V / VCC levels; no active pullup circuit |
| 4 - OUT | Gate drive output | Noninverting output capable of sourcing/sinking up to 2 A peak into capacitive loads |
| 5 - VCC | Driver supply rail | Primary power input (4–14 V); powers both input stage and BiCMOS output stage |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | ≤15 µA ICC with static IN high/low - extends battery life in portable or energy-sensitive systems |
| High-speed BiCMOS output | 25-ns max tr/tf into 1-nF load - reduces MOSFET switching losses and EMI generation |
| Robust input threshold hysteresis | 1.3 V - prevents chatter during slow-rising input edges and improves noise immunity |
| Latch-up resistant design | Qualified per JEDEC JESD78 - withstands overvoltage transients without destructive latch-up |
| Wide temperature operation | –40°C to 125°C ambient - supports deployment in harsh thermal environments without derating |
Applications
| Switch-Mode Power Supply (SMPS) | Motor Gate Driver Stage |
|---|---|
Use Scenario: Driving high-side N-channel MOSFET in synchronous buck converter operating at 500 kHz–1 MHz. IC Role / Device Role / Timing Role: Noninverting gate driver translating PWM controller output to full-swing gate voltage with minimal propagation skew. Use Value: 25-ns rise time and 40-ns propagation delay enable precise dead-time control and reduce conduction losses by minimizing overlap regions. |
Use Scenario: Controlling gate of half-bridge MOSFET pair in 24-V BLDC motor driver. IC Role / Device Role / Timing Role: High-current, low-latency buffer isolating MCU GPIO from power stage while maintaining signal integrity. Use Value: 2-A peak output sustains fast turn-on even with 3-nF total gate charge, and ≤15-µA ICC avoids loading low-power microcontroller supply rails. |
| Industrial PLC Output Module | LED Driver Switching Stage |

Use Scenario: Gate-driving MOSFET in constant-current LED boost converter for architectural lighting. IC Role / Device Role / Timing Role: Fast-switching interface between PWM dimming controller and power switch. Use Value: Low ICC allows direct connection to low-power MCU I/O without additional LDO; 1.3-V input hysteresis rejects line noise in noisy lighting fixtures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2817DBVT | Includes internal active pullup on IN and voltage regulator (VDD functional); ICC ≈ 25–50 µA | Supports open-collector PWM controllers (e.g., TL5001) without external pullup; accepts 14–40 V on VDD | Select when regulator output or active pullup is required; not drop-in due to VDD functionality and higher ICC |
| UCC27517DBVR | Higher 4-A peak output, 17-V max VDD, integrated negative voltage handling, 10-ns typ tr/tf | Targets higher-power, higher-frequency designs requiring faster edge rates and robust shoot-through protection | Choose for >1-MHz operation or enhanced ruggedness; requires layout review due to different pinout and higher drive capability |
Compared with TPS2829DBVT, TPS2817DBVT adds regulator and pullup functionality at the cost of higher quiescent current and VDD dependency, while UCC27517DBVR delivers superior speed and drive strength but with increased complexity and cost-making TPS2829DBVT optimal for cost-sensitive, low-power, fixed-rail gate driving.

FAQ
What is the function of Pin 1 (VDD) on the TPS2829DBVT?
Pin 1 (VDD) on the TPS2829DBVT is a no-connect (NC) terminal. Unlike TPS2817/TPS2819, the TPS2829DBVT omits the internal voltage regulator, so VDD has no internal connection and must remain unconnected in PCB layout. This simplifies design by removing regulator-related components and reduces quiescent current to ≤15 µA.
Does the TPS2829DBVT support open-collector input controllers without external pullup resistors?
No, the TPS2829DBVT does not include an active pullup circuit on its IN pin. It requires an external pullup resistor when interfacing with open-collector or open-drain PWM controllers (e.g., TL5001). In contrast, TPS2816/TPS2817 integrate active pullup; the TPS2829DBVT's design prioritizes ultra-low ICC over input convenience.
What is the maximum capacitive load the TPS2829DBVT can drive while maintaining specified rise/fall times?
The TPS2829DBVT's 25-ns max rise/fall time specification is guaranteed with a 1-nF capacitive load, per the datasheet test condition. While it can drive larger loads (e.g., 2.2 nF), actual tr/tf will increase proportionally-measured at 35 ns for 2.2 nF at VCC = 5 V. For loads >1 nF, verify timing margins in system-level simulation or bench testing.
Can the TPS2829DBVT operate with a 3.3-V supply voltage?
No, the TPS2829DBVT has a minimum supply voltage of 4 V per its recommended operating conditions. At 3.3 V, the BiCMOS output stage cannot reliably achieve rail-to-rail swing or sustain 2-A peak current. For 3.3-V systems, consider alternatives like TI's UCC27517 (supports 2.7–17 V) or dual-supply gate drivers with level-shifting.
Is the TPS2829DBVT pin-compatible with other devices in the TPS28xx family?
The TPS2829DBVT shares the same 5-pin SOT-23 (DBV) footprint and pin numbering as TPS2817DBVT and TPS2819DBVT, but it is not functionally pin-compatible due to the NC VDD pin and absence of internal regulator/pullup. Swapping requires schematic and layout revision to remove VDD connections and add external pullup if needed.
