Product details
Overview
TPS2819MDBVREP from Texas Instruments is a noninverting single-channel high-speed MOSFET driver in a 5-pin SOT-23 (DBV) package, delivering up to 2 A peak output current with 25 ns max rise/fall times and 40 ns max propagation delay into 1 nF load. It features an internal voltage regulator (8–40 V input), operates from –55°C to 125°C, and is designed for high-frequency switching converters driving power MOSFETs.
For engineers reviewing the TPS2819MDBVREP datasheet, TPS2819MDBVREP pinout, TPS2819MDBVREP application, or TPS2819MDBVREP equivalent, key selection considerations include its noninverting logic configuration, regulator-enabled wide-input operation (up to 40 V), BiCMOS output stage for fast edge control, and extended temperature qualification for aerospace and defense systems.
Technical Context
The TPS2819MDBVREP uses a BiCMOS output stage to achieve high instantaneous drive current while minimizing shoot-through. Its input threshold is approximately 2/3 VCC for positive-going transitions and 1/3 VCC for negative-going transitions, with 1.3 V hysteresis - enabling robust noise immunity in noisy power-converter environments.
Unlike TPS2817, this device omits the active pullup circuit, resulting in sub-50 µA total operating current. The integrated series regulator provides a stable ~11.5 V output at up to 20 mA, usable to power external PWM controllers or bias circuitry when VDD is supplied between 8 V and 40 V.
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., >2 nF) |
| Rise/fall time | 25 ns max (1 nF load) - enables >10 MHz switching in optimized layouts |
| Propagation delay | 40 ns max (1 nF load) - supports tight timing control in synchronous buck or half-bridge topologies |
| Regulator input range | 8 V to 40 V on VDD - allows direct connection to unregulated 24 V or 36 V rails |
| Operating temperature | –55°C to 125°C ambient - qualified per JEDEC HAST, temperature cycle, and autoclave testing |
| Supply voltage (VCC) | 4 V to 14 V - defines core driver rail; regulator output powers internal circuitry and optional external loads |
Pinout & Package
TPS2819MDBVREP is housed in a 5-pin SOT-23 (DBV) package, tape-and-reel packaged (3000 units/reel), RoHS-compliant with NiPdAu lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Regulator supply input | Accepts 8–40 V to power internal regulator; not connected if regulator unused (tie to VCC) |
| GND | Ground reference | Common return for driver outputs, regulator, and input logic; must be low-inductance path |
| IN | Logic input | CMOS-compatible input (no active pullup); accepts –0.3 V to VCC + 0.5 V; hysteresis improves noise margin |
| OUT | Power output | Drives MOSFET gate directly; capable of ±2 A peak; output swing is rail-to-rail (0 V to VCC) |
| VCC | Driver supply / regulator output | Supplies 4–14 V to driver core; also serves as regulated 11.5 V output (20 mA max) when VDD is applied |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS output stage | Delivers 2 A peak current with low saturation voltage (<1 V at 100 mA), minimizing gate-drive losses |
| Integrated series regulator | Accepts 8–40 V on VDD and delivers regulated 11.5 V @ 20 mA - eliminates need for external LDO in multi-rail systems |
| No active pullup circuit | Reduces quiescent current vs. TPS2817; enables use with push-pull or CMOS-level controllers without external biasing |
| Latch-up resistant design | Qualified per JEDEC JESD78; withstands >100 mA injected current without functional interruption |
| High-speed timing performance | 25 ns max tr/tf and 40 ns max tPLH/tPHL ensure minimal dead-time uncertainty in synchronous rectification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2817MDBVREP | Includes active pullup input circuit; higher ICC (~650 µA at VCC = 10 V, IN = 0 V) | Better suited for open-collector PWM controllers (e.g., TL5001) without external pullup resistors | Select TPS2817MDBVREP only when interfacing with open-drain/open-collector controllers requiring guaranteed high-state input bias |
| TPS2829MDBVREP | Omits internal regulator and active pullup; ICC < 15 µA (IN high/low); no VDD pin | Optimized for ultra-low-quiescent-current 4–14 V systems where external regulation is already present | Choose TPS2829MDBVREP when VCC is tightly regulated and board space/power budget preclude using the integrated regulator |
Compared with TPS2817MDBVREP, TPS2819MDBVREP offers lower input bias current and no active pullup - simplifying interface with CMOS drivers but requiring external pullup if used with open-collector sources. Versus TPS2829MDBVREP, it adds regulator capability at the cost of higher quiescent current and one extra pin (VDD), making it ideal for systems needing both gate drive and auxiliary bias generation.

FAQ
What is the function of the VDD pin on the TPS2819MDBVREP?
The VDD pin on the TPS2819MDBVREP is the input to the internal series voltage regulator. When supplied with 8–40 V, it enables the device to generate a regulated ~11.5 V output on the VCC pin, usable for powering external circuitry. If the regulator is unused, VDD must be tied to VCC - leaving it floating or grounded will damage the device.
Does the TPS2819MDBVREP support inverting logic configuration?
No, the TPS2819MDBVREP is a noninverting driver: its output follows the input logic state (OUT = IN). For inverting functionality, TI specifies the TPS2818MDBVREP as the functional counterpart within the same family and package.
What is the maximum continuous output current rating for the TPS2819MDBVREP?
The TPS2819MDBVREP is rated for ±100 mA continuous output current per the Absolute Maximum Ratings table. Its 2 A peak current capability applies only to transient gate-charge pulses; sustained DC loading beyond ±100 mA risks exceeding thermal limits and violating SOA constraints.
Can the TPS2819MDBVREP drive GaN FETs effectively?
Yes, the TPS2819MDBVREP can drive enhancement-mode GaN FETs effectively due to its 2 A peak output current, 25 ns rise/fall times, and rail-to-rail output swing. Its 1.3 V input hysteresis and BiCMOS output stage provide noise immunity and low gate-drive impedance - critical for preventing spurious turn-on in high-dV/dt GaN applications.
How does the TPS2819MDBVREP differ from the commercial-grade TPS2819DBV?
The TPS2819MDBVREP is the enhanced-product (EP) version: it undergoes extended temperature qualification (–55°C to 125°C), controlled baseline manufacturing (single assembly/test/fab site), and enhanced DMS support. The commercial TPS2819DBV is rated only from –40°C to 85°C and lacks the EP pedigree documentation and long-term availability guarantees.
