Product details
Overview
TPS2816DBVR from Texas Instruments is an inverting single-channel high-speed MOSFET driver with active pullup input, 2-A peak output current, 14-ns typical rise/fall time (VCC = 10 V, CL = 1 nF), internal voltage regulator (11.5-V typ output), and 5-pin SOT-23 package. It enables fast switching in high-frequency DC/DC converters driving N-channel MOSFETs.
For engineers reviewing the TPS2816DBVR datasheet, TPS2816DBVR pinout, TPS2816DBVR application, or TPS2816DBVR equivalent, key selection criteria include inverting logic behavior with integrated active pullup, regulator-enabled operation up to 40-V VDD input, BiCMOS output stage for rail-to-rail drive, and –40°C to 125°C ambient temperature rating.
Technical Context
The TPS2816DBVR uses a BiCMOS output stage to deliver up to 2 A peak current while maintaining low output saturation voltages (≤2 V at 100 mA sink/source). Its input stage includes an active pullup circuit eliminating external bias resistors for open-collector PWM controllers like TL5001.
An internal series regulator accepts VDD inputs from 8 V to 40 V and delivers a regulated ~11.5-V output at up to 20 mA, usable to power auxiliary circuitry. Input thresholds are CMOS-compatible: ≈2/3 VCC for positive-going and ≈1/3 VCC for negative-going transitions, with 1.3-V hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output polarity | Inverting: OUT = NOT(IN); required for gate drive in synchronous buck high-side configurations with certain controllers. |
| Rise/fall time | 14 ns typical (VCC = 10 V, CL = 1 nF); enables >10 MHz switching in low-capacitance gate drive paths. |
| Propagation delay | 24 ns typical (tPLH/tPHL, VCC = 10 V); ensures precise timing alignment in high-frequency PWM systems. |
| Peak output current | 2 A; sufficient to charge/discharge MOSFET gates with >2 nF total gate charge within nanoseconds. |
| Regulator output | 11.5 V ±1.5 V (10–13 V range), 20 mA max; powers external ICs (e.g., PWM controller) without secondary LDO. |
| Supply voltage range | VCC = 4–14 V; VDD = 8–40 V (regulator input); supports wide-input industrial and automotive DC/DC designs. |
| Operating temperature | –40°C to 125°C ambient; qualified for under-hood and industrial motor control environments. |
Pinout & Package
TPS2816DBVR is housed in a 5-pin SOT-23 (DBV) package, surface-mount, tape-and-reel compatible (3000 pcs/reel), RoHS-compliant with NiPdAu lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Regulator supply input | Accepts 8–40 V to power internal regulator; not connected if regulator unused (tie to VCC). |
| GND (Pin 2) | Power ground reference | Common return for VCC, VDD, and output stage; must be low-inductance connection to minimize shoot-through. |
| IN (Pin 3) | Inverting logic input | Active-pullup input accepts open-collector signals; threshold ≈2/3 VCC (rising), ≈1/3 VCC (falling). |
| OUT (Pin 4) | Driver output | BiCMOS totem-pole output drives MOSFET gate; 2-A peak, rail-to-rail swing (0.18 V low / 9.1 V high @ 100 mA). |
| VCC (Pin 5) | Driver supply / regulator output | Supplies output stage (4–14 V); also outputs regulated 11.5 V when VDD is applied and regulator enabled. |
Key Features
| Feature | Design Value |
|---|---|
| Inverting logic with active pullup | Eliminates external pullup resistor for TL5001/UC384x-style open-collector PWM controllers, reducing BOM count and board space. |
| Integrated 11.5-V series regulator | Enables single-supply operation from 8–40 V VDD while delivering regulated voltage to power external ICs-no second LDO needed. |
| 2-A BiCMOS output stage | Delivers high instantaneous current to rapidly charge/discharge large MOSFET gates (e.g., TPS1110), cutting switching losses. |
| 14-ns typical rise/fall time | Supports >10-MHz gate drive in high-efficiency SMPS designs where fast edge rates reduce conduction time and EMI. |
| Latch-up resistant design | Qualified per JEDEC JESD78; withstands transient overvoltage events common in motor drive and converter power stages. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2817DBVR | Noninverting logic; identical regulator, timing, and output specs; no active pullup on TPS2817 (standard CMOS input). | Used where controller outputs active-high PWM (e.g., UC384x with pullup); requires external pullup if interfacing open-collector sources. | Select TPS2817DBVR only when noninverting behavior matches controller architecture and external pullup is acceptable. |
| TPS2828DBVR | No internal regulator or active pullup; quiescent current <15 µA (vs. 650 µA low-state for TPS2816DBVR); same 2-A output and timing. | Suitable for low-power, fixed 4–14 V supply systems where regulator functionality is unnecessary and ultra-low ICC is critical. | Choose TPS2828DBVR only when VDD >14 V is unused and system-level power budget prohibits regulator overhead. |
Compared with TPS2817DBVR, TPS2816DBVR provides guaranteed active pullup for open-collector interfaces but consumes higher quiescent current in low state; versus TPS2828DBVR, it adds regulator flexibility at the cost of higher static power and one extra functional block.

FAQ
What is the logic polarity of the TPS2816DBVR?
The TPS2816DBVR is an inverting driver: when the IN pin is high, the OUT pin is low, and vice versa. This behavior is fixed and inherent to the device's input stage design. The TPS2816DBVR does not support configuration or mode selection - its inverting function is hardwired and used in applications such as high-side N-MOSFET drive with open-collector PWM controllers.
Can the TPS2816DBVR operate without connecting VDD?
Yes - the TPS2816DBVR can operate with VDD unconnected (floating) or tied directly to VCC. When VDD is not used, the internal regulator is disabled and the device functions as a standard 4–14 V VCC-powered driver. However, doing so forfeits the 8–40 V extended input capability and regulated 11.5-V auxiliary output. The TPS2816DBVR remains fully functional for VCC-only operation.
What is the maximum continuous output current rating for the TPS2816DBVR?
The TPS2816DBVR is rated for ±100 mA continuous output current per Absolute Maximum Ratings, but delivers up to 2 A peak current for short durations (nanoseconds) into capacitive loads like MOSFET gates. The 2-A peak is validated under CL = 1 nF, VCC = 10 V, and TA = 25°C. Continuous DC current must remain ≤100 mA to avoid exceeding thermal limits in the SOT-23 package.
Does the TPS2816DBVR require an external pullup resistor on the IN pin?
No - the TPS2816DBVR includes an integrated active pullup circuit on the IN pin, explicitly designed to eliminate the need for an external pullup resistor when interfacing with open-collector or open-drain PWM controllers (e.g., TL5001, UC3842). This feature reduces component count and improves signal integrity in high-noise power supply environments.
What is the purpose of the VDD pin on the TPS2816DBVR?
The VDD pin on the TPS2816DBVR supplies the internal series regulator, which generates a regulated ~11.5-V output at Pin 5 (VCC) and supports up to 20 mA of auxiliary current. With VDD connected to 8–40 V, the TPS2816DBVR operates across wider input ranges and powers external circuitry - a capability absent in non-regulator variants like TPS2828DBVR. Grounding VDD will destroy the regulator.
