Product details
Overview
TPS2817DBVT from Texas Instruments is a noninverting single-channel high-speed MOSFET driver with active pullup input, 2-A peak output current, 24–45 ns propagation delay (VCC = 10 V), and integrated 11.5-V regulator supporting 14–40 V VDD input. It operates across –40°C to 125°C and drives power stages in DC-DC converters.
For engineers reviewing the TPS2817DBVT datasheet, TPS2817DBVT pinout, TPS2817DBVT application, or TPS2817DBVT equivalent, this page delivers verified electrical specs, package mapping, functional role in gate-drive circuits, thermal limits, and validated alternatives for industrial switching power supply design.
Technical Context
The TPS2817DBVT uses a BiCMOS output stage to achieve fast switching (14 ns typical rise/fall) while minimizing shoot-through current through inherent logic design. Its input stage includes an active pullup circuit, eliminating external resistors when interfacing with open-collector PWM controllers like TL5001.
An internal series regulator accepts 14–40 V on VDD and delivers a stable ~11.5 V at up to 20 mA to VCC, enabling operation from wide-input supplies and powering auxiliary circuitry-subject to 437 mW total dissipation limit at TA ≤ 25°C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2819DBVR | No active pullup; CMOS input draws <50 µA quiescent current; identical regulator and output specs | Better suited for low-power standby modes where input leakage must be minimized | Select TPS2819DBVR when interfacing with push-pull controllers or when ultra-low input current is critical |
| UCC27524ADRMR | Higher 5-A peak output; dual-channel; no integrated regulator; 4–16 V VDD range; 17 ns max propagation delay | Designed for high-efficiency, multi-phase SMPS with tight timing synchronization requirements | Choose UCC27524ADRMR for higher-current, dual-MOSFET, or regulator-free architectures needing tighter timing control |
Compared with TPS2817DBVT, TPS2819DBVR removes the active pullup for lower input bias but loses open-collector compatibility, while UCC27524ADRMR trades regulator integration for higher drive strength and dual-channel capability-making each optimal for distinct power-stage topologies.

FAQ
What is the maximum VDD voltage the TPS2817DBVT regulator can accept?
The TPS2817DBVT regulator accepts up to 40 V on the VDD pin, with recommended operation from 14 V to 40 V. Exceeding 42 V violates absolute maximum ratings and risks permanent damage. At VDD = 40 V, the regulator delivers ~11.5 V to VCC while maintaining ≤20 mA output capability, provided total power dissipation stays within the 437 mW limit at TA ≤ 25°C.
Does the TPS2817DBVT require an external pullup resistor on its IN pin?
No, the TPS2817DBVT includes an integrated active pullup circuit on the IN pin, explicitly eliminating the need for an external pullup resistor when interfacing with open-collector or open-drain PWM controllers such as TL5001. This feature reduces BOM count and layout complexity while ensuring reliable logic-level translation without signal degradation.
Can the TPS2817DBVT drive both N-channel and P-channel MOSFETs?
Yes, the TPS2817DBVT can drive either N-channel or P-channel MOSFETs, depending on circuit configuration. As a noninverting driver, it sources current to turn on high-side N-MOSFETs (when used with level-shifting bootstrap or isolated supply) or sinks current to turn on low-side P-MOSFETs. Its rail-to-rail output swing (0.18 V to 9.1 V @ 100 mA) ensures full enhancement across common gate-threshold ranges.
What is the thermal limitation of the TPS2817DBVT in continuous operation?
The TPS2817DBVT has a maximum power dissipation of 437 mW at TA ≤ 25°C in the SOT-23-5 (DBV) package, derating linearly at 3.5 mW/°C above that temperature. At TA = 70°C, usable dissipation drops to 280 mW. To maintain reliability, PCB layout must include adequate copper pour on GND and thermal vias beneath the exposed pad (if used), especially when delivering sustained 2-A peak currents into heavy capacitive loads.
How does the TPS2817DBVT differ from the TPS2816DBVT?
The TPS2817DBVT is the noninverting counterpart to the inverting TPS2816DBVT; both share identical regulator, output drive, timing, and thermal specifications. The key functional difference lies in logic polarity: TPS2817DBVT outputs HIGH when input is HIGH, while TPS2816DBVT outputs LOW when input is HIGH. Both include active pullup and operate across –40°C to 125°C in the same DBV package.
