Product details
Overview
TPS2816DBVT from Texas Instruments is an inverting single-channel high-speed MOSFET driver with active pullup input, 2-A peak output current, 25-ns max rise/fall time (1-nF load), 40-ns max propagation delay, and integrated 11.5-V series regulator supporting up to 40-V VDD input-designed for gate driving in high-frequency DC/DC converters.
For engineers reviewing the TPS2816DBVT datasheet, TPS2816DBVT pinout, TPS2816DBVT application, or TPS2816DBVT equivalent, key selection considerations include its inverting logic behavior, active pullup eliminating external bias resistors for open-collector PWM controllers, regulator-enabled operation above 14 V, BiCMOS output stage, and SOT-23-5 thermal performance at –40°C to 125°C.
Technical Context
The TPS2816DBVT implements a BiCMOS push-pull output stage delivering ±2-A peak current into capacitive loads, with CMOS-compatible input thresholds (≈2/3 VCC for rising edge, ≈1/3 VCC for falling edge) and inherent shoot-through minimization. Its internal series regulator accepts 8–40 V on VDD and delivers regulated 11.5 V at up to 20 mA to VCC.
Input stage includes an active pullup circuit enabling direct interface with open-collector PWM controllers (e.g., TL5001) without external resistors. The device operates as an inverting driver: OUT = NOT(IN), with GND-referenced logic and rail-to-rail output swing limited by VCC and ground.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Inverting driver: output state is logical complement of input; enables direct use with open-drain/open-collector controllers. |
| Peak Output Current | ±2 A - sufficient to rapidly charge/discharge MOSFET gates up to ~3 nF, reducing switching losses in high-frequency power stages. |
| Rise/Fall Time | 25 ns max (CL = 1 nF, VCC = 10 V) - supports >10 MHz switching in optimized layouts with minimal gate loop inductance. |
| Propagation Delay | 40 ns max (high-to-low and low-to-high) - ensures tight timing control in synchronous buck, half-bridge, and resonant topologies. |
| Regulator Output | 11.5 V ±1.5 V (VDD = 14–40 V, IO ≤ 20 mA) - powers internal circuitry and can supply auxiliary rails (e.g., PWM controller VCC) within package power limits. |
| Supply Voltage Range | VCC = 4–14 V; VDD = 8–40 V - enables wide-input industrial and automotive DC/DC designs without external LDOs. |
| Operating Temperature | –40°C to +125°C ambient - qualified for under-hood, motor control, and industrial power applications with full parameter guarantees. |
Pinout & Package
SOT-23-5 (DBV) package: 5-pin surface-mount, tape-and-reel (250 pcs/reel), moisture sensitivity level 1, RoHS-compliant, NIPDAU lead finish, 1.37 mm cavity depth, Q3 pin-1 quadrant orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Regulator input supply | Accepts 8–40 V; powers internal regulator; must not be grounded - destruction occurs if shorted to GND. |
| GND (Pin 2) | Power and signal reference | Common return for VCC, VDD, IN, and OUT; requires low-inductance connection to minimize ground bounce. |
| IN (Pin 3) | Inverting logic input | CMOS-compatible with active pullup; eliminates need for external pullup when interfacing with open-collector controllers. |
| OUT (Pin 4) | Driver output | Push-pull BiCMOS stage; drives MOSFET gate directly; rated for ±100 mA continuous, ±2 A peak. |
| VCC (Pin 5) | Driver supply / regulator output | Supplies output stage; sourced internally by regulator (when VDD applied) or externally (if VDD tied to VCC); max 14 V. |
Key Features
| Feature | Design Value |
|---|---|
| Active pullup input | Eliminates external pullup resistor for open-collector PWM controllers (e.g., TL5001), reducing BOM count and board space. |
| Integrated 11.5-V regulator | Enables single-supply operation from 14–40 V bus while powering VCC and external ICs - no external LDO required. |
| BiCMOS output stage | Delivers 2-A peak current with <1-V saturation at 100 mA, minimizing conduction loss during gate transitions. |
| High noise immunity | 1.3-V input hysteresis and latch-up resistance ensure robust operation in electrically noisy power-converter environments. |
| Thermal robustness | Rated for 125°C ambient with 437 mW power dissipation at 25°C and 3.5 mW/°C derating - supports compact, sealed power modules. |
Applications
| Motor Drive Gate Control | Isolated DC/DC Converter Driver |
|---|---|
Use Scenario: Driving high-side N-channel MOSFETs in 3-phase BLDC inverters using isolated gate drivers or bootstrap configurations.

IC Role / Device Role / Timing Role: Inverting gate driver accepting 12-V battery input (via VDD regulator) and driving N-channel load switches. Use Value: Regulator withstands load-dump transients up to 40 V; –40°C to 125°C rating meets AEC-Q100 ambient requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2817DBVT | Noninverting logic function; identical regulator, timing, and drive specs; same SOT-23-5 package. | Used where controller output polarity matches required gate drive (e.g., direct PWM-to-gate without inversion). | Select TPS2817DBVT when system-level logic requires noninverting behavior - no change to layout or thermal design. |
| TPS2818DBVT | Same inverting logic and timing as TPS2816DBVT but omits active pullup and regulator; VDD pin is NC. | Targeted at low-quiescent-current (<50 µA) 4–14 V systems where external regulation and pullup are already provided. | Choose TPS2818DBVT only if regulator and pullup functions are redundant - saves cost but forfeits 8–40 V operation and open-collector compatibility. |
Compared with TPS2817DBVT, TPS2816DBVT provides inverting logic essential for certain feedback-controlled topologies; compared with TPS2818DBVT, it retains the regulator and active pullup - critical for wide-input and open-collector interface applications.

FAQ
What is the logic configuration of the TPS2816DBVT?
The TPS2816DBVT is an inverting driver: when the IN pin is high, the OUT pin is low, and vice versa. This configuration enables direct interface with open-collector PWM controllers like the TL5001 without external logic inversion. Its input includes an active pullup circuit, eliminating the need for an external pullup resistor - a key differentiator from noninverting variants such as the TPS2817DBVT.
Can the TPS2816DBVT operate from a 24-V input bus?
Yes - the TPS2816DBVT supports VDD inputs from 8 V to 40 V. When supplied with 24 V on VDD, its internal series regulator delivers a stable 11.5 V (±1.5 V) at up to 20 mA to the VCC pin, which powers the output stage and can also supply auxiliary circuits. This eliminates the need for an external LDO in wide-input industrial or automotive power designs.
What is the maximum continuous output current rating for the TPS2816DBVT?
The TPS2816DBVT is rated for ±100 mA continuous output current per the Absolute Maximum Ratings table. However, it delivers ±2 A peak current for short durations (nanosecond-scale) to charge/discharge MOSFET gate capacitance. Continuous current capability is thermally limited by package dissipation (437 mW at 25°C, derated 3.5 mW/°C), making layout and PCB copper area critical for sustained high-current operation.
How does the active pullup feature benefit system design?
The active pullup circuit on the IN pin of the TPS2816DBVT allows direct connection to open-collector or open-drain PWM controller outputs (e.g., TL5001) without an external pullup resistor. This reduces component count, saves board space, eliminates resistor tolerance drift effects, and improves reliability - especially in high-vibration or thermally cycling environments where passive components may degrade.
Is the TPS2816DBVT pin-compatible with other devices in the TPS28xx family?
Yes - all TPS28xx devices (TPS2816/17/18/19/28/29) share identical SOT-23-5 (DBV) pinouts and mechanical footprints. However, functional differences exist: TPS2816DBVT has inverting logic with active pullup and regulator; TPS2817DBVT is noninverting with same features; TPS2818DBVT is inverting without regulator or pullup. Electrical compatibility requires verifying logic polarity and supply architecture before substitution.
