Product details
Overview
TPS2818DBVR from Texas Instruments is an inverting single-channel high-speed MOSFET driver IC designed for gate driving in switching power supplies and motor control circuits. It delivers 2-A peak output current, supports 4-V to 14-V driver supply voltage (with internal regulator extending input range to 40 V), achieves ≤25-ns rise/fall times at 1-nF load, and operates across –40°C to 125°C ambient temperature in a 5-pin SOT-23 package.
For engineers reviewing the TPS2818DBVR datasheet, TPS2818DBVR pinout, TPS2818DBVR application, or TPS2818DBVR equivalent, this page provides verified functional identity, confirmed pin functions, regulator-enabled high-voltage operation capability, BiCMOS output stage performance data, and real-world switching converter use cases - all specific to the TPS2818DBVR variant without conflating features of TPS2816/TPS2817/TPS2828/TPS2829.
Technical Context
The TPS2818DBVR implements an inverting logic function with CMOS-compatible input thresholds (≈2/3 VCC for positive-going, ≈1/3 VCC for negative-going) and no active pullup circuit - distinguishing it from TPS2816/TPS2817. Its 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 for auxiliary circuitry.
The BiCMOS output stage enables fast edge transitions while minimizing shoot-through current via inherent design. Input hysteresis is 1.3 V, input leakage is ≤0.2 µA at VCC or GND, and absolute maximum ratings include VCC = –0.3 V to 15 V and VDD = VCC –0.3 V to 42 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Inverting driver: OUT = NOT(IN); no active pullup on input |
| Peak Output Current | 2 A - sufficient to rapidly charge/discharge large MOSFET gate capacitances (e.g., >1 nF) |
| Rise/Fall Time | ≤25 ns max at VCC = 10 V, CL = 1 nF - enables >10 MHz switching in optimized layouts |
| Propagation Delay | ≤45 ns max (tPLH/tPHL) at VCC = 10 V, CL = 1 nF - critical for tight timing control in synchronous converters |
| Supply Voltage Range | VCC = 4 V to 14 V; VDD = 8 V to 40 V (regulator input) - supports wide-input industrial DC-DC designs |
| Regulator Output | 10 V to 13 V at 0–20 mA - powers PWM controllers or bias circuits without external LDO |
| Operating Temp | –40°C to 125°C ambient - qualified for under-hood automotive and industrial power stages |
Pinout & Package
TPS2818DBVR is housed in a 5-pin SOT-23 (DBV) package, surface-mount, tape-and-reel compatible (3000 pcs/reel). Pin 1 is VDD (regulator input), Pin 2 is GND, Pin 3 is IN (inverting logic input), Pin 4 is OUT (driver output), and Pin 5 is VCC (driver supply/regulator output).
| 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) | Ground reference | Common return for regulator, driver, and logic; must be low-inductance connection |
| IN (Pin 3) | Inverting logic input | CMOS-compatible input with 1.3 V hysteresis; no internal pullup - requires external bias if open-collector source |
| OUT (Pin 4) | Driver output | BiCMOS totem-pole output capable of ±2 A peak; drives MOSFET gate directly |
| VCC (Pin 5) | Driver supply / regulator output | Supplies driver core; also outputs regulated ~11.5 V when VDD is applied |
Key Features
| Feature | Design Value |
|---|---|
| Inverting logic with no active pullup | Eliminates need for external pullup only when driven by push-pull sources; requires external bias for open-collector inputs |
| Integrated 40-V tolerant regulator | Enables direct connection to wide-input bus (e.g., 24 V, 36 V, 48 V systems) while powering driver and external ICs at stable ~11.5 V |
| BiCMOS output stage | Delivers 2-A peak current with <25-ns edges and low rail-to-rail drop - reduces MOSFET switching losses |
| High latch-up immunity | Rated per JEDEC JESD78; survives transient overvoltage events common in power electronics without destructive latch-up |
| –40°C to 125°C operation | Validated across full industrial temperature range - suitable for enclosed power modules and motor drives |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2819DBVR | Noninverting logic function; identical regulator, timing, and output specs | Requires inverted PWM signal or external inverter; eliminates need for logic inversion in controller firmware/hardware | Select TPS2819DBVR when system-level signal polarity matches noninverting requirement and layout permits |
| TPS2828DBVR | No internal regulator; quiescent current <15 µA; same inverting logic and 2-A output | Restricted to 4–14 V VCC operation; unsuitable for >14 V input rails unless external regulation provided | Choose TPS2828DBVR only in low-quiescent, low-voltage (<14 V) applications where regulator functionality is unnecessary |
Compared with TPS2819DBVR, TPS2818DBVR provides inverting logic without added components but requires matching controller output polarity; compared with TPS2828DBVR, it adds regulator capability at the cost of higher quiescent current - making it optimal for wide-input industrial power stages needing auxiliary bias.

FAQ
What is the logic function of the TPS2818DBVR?
The TPS2818DBVR is an inverting MOSFET driver: its output state is the logical inverse of the input signal (OUT = NOT(IN)). Unlike TPS2816/TPS2817, it lacks an internal active pullup circuit, so the input requires defined logic levels - either push-pull drive or external biasing for open-collector sources. This behavior is explicitly confirmed in the SLVS160C datasheet's functional description and terminal table.
Does the TPS2818DBVR include an internal voltage regulator?
Yes, the TPS2818DBVR includes an internal series regulator that accepts VDD inputs from 8 V to 40 V and delivers a regulated output of 10 V to 13 V at up to 20 mA on the VCC pin. This regulator is shared with TPS2816/TPS2817/TPS2819 and is absent only in TPS2828/TPS2829 variants. The regulator is fully functional in TPS2818DBVR and documented in both the "Regulator" electrical characteristics table and application diagrams.
What are the absolute maximum voltage ratings for TPS2818DBVR pins?
The absolute maximum ratings for TPS2818DBVR are: VCC = –0.3 V to 15 V; VDD = VCC –0.3 V to 42 V; IN = –0.3 V to VCC +0.5 V; and OUT = –0.5 V to VCC +0.5 V - all referenced to GND. These values are specified in the SLVS160C datasheet Section 4 ("Absolute Maximum Ratings") and apply strictly to the TPS2818DBVR variant, consistent across the TPS2816–TPS2819 group.
Can TPS2818DBVR drive a 1000-pF MOSFET gate capacitance with fast switching?
Yes, the TPS2818DBVR is characterized for 1-nF load (1000 pF) with ≤25-ns rise/fall times and ≤45-ns propagation delay at VCC = 10 V. Its 2-A peak output current ensures rapid gate charging/discharging, and typical rise time remains ≤14 ns at VCC = 10 V per Figure 4. This performance is validated in the "Switching Characteristics" section of SLVS160C and applies directly to TPS2818DBVR.
What is the operating temperature range for TPS2818DBVR?
The TPS2818DBVR is rated for an operating ambient temperature range of –40°C to 125°C, as confirmed in the "Recommended Operating Conditions" table (Section 4) and "Available Options" table of the SLVS160C datasheet. This range is identical across all DBV-packaged TPS2816–TPS2819 devices and is supported by thermal derating data in the Dissipation Rating Table.
