Product details
Overview
TPS2819DBVT from Texas Instruments is a noninverting single-channel high-speed MOSFET driver in a 5-pin SOT-23 package, delivering 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 (VDD input, 11.5-V typical output) enabling operation up to 40 V supply, and operates across –40°C to 125°C ambient temperature for industrial DC-DC converter gate drive.
For engineers reviewing the TPS2819DBVT datasheet, TPS2819DBVT pinout, TPS2819DBVT application, or TPS2819DBVT equivalent, key selection criteria include regulated 11.5-V VCC output capability, noninverting logic polarity, absence of active pullup (vs. TPS2817), and compatibility with high-frequency synchronous buck topologies requiring low shoot-through risk and BiCMOS output stage performance.
Technical Context
The TPS2819DBVT uses a BiCMOS output stage to achieve fast switching (tr/tf ≤ 25 ns) while minimizing shoot-through current through inherent design. Its input threshold is CMOS-compatible - approximately 2/3 VCC for positive-going and 1/3 VCC for negative-going transitions - with 1.3-V hysteresis ensuring noise immunity.
It integrates a series-connected voltage regulator accepting VDD inputs from 8 V to 40 V and delivering a stable ~11.5-V output at up to 20 mA, usable to power external circuitry (e.g., PWM controllers) within package thermal limits. Unlike TPS2817DBVT, it omits the active pullup input circuit, resulting in <50 µA typical supply current (VCC) when inputs are static.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Driver Type | Noninverting single-channel MOSFET driver - output follows input logic state (OUT = IN) |
| Peak Output Current | 2 A - sufficient to rapidly charge/discharge large MOSFET gate capacitances (e.g., >1 nF) in high-frequency converters |
| Rise/Fall Time (max) | 25 ns @ VCC = 10 V, CL = 1 nF - enables >10 MHz effective switching in optimized layouts |
| Propagation Delay (max) | 40 ns @ VCC = 10 V, CL = 1 nF - supports tight timing control in synchronous rectification and phase-shifted topologies |
| Regulator Output | 11.5 V typical @ VDD = 14–40 V, IO ≤ 20 mA - powers auxiliary ICs (e.g., TL5001) without external LDO |
| Supply Voltage Range | VCC: 4–14 V; VDD: 8–40 V - allows direct connection to 12-V rails or higher-voltage bus with regulation |
| Operating Temperature | –40°C to 125°C ambient - qualified for under-hood automotive auxiliary supplies and industrial power modules |
Pinout & Package
TPS2819DBVT is housed in a 5-pin SOT-23 (DBV) package, tape-and-reel packaged (250 units/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 enable 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) | Logic input | CMOS-compatible input (no active pullup); thresholds at ~1/3 VCC (low-to-high) and ~2/3 VCC (high-to-low) |
| OUT (Pin 4) | High-current gate drive output | Delivers ±2 A peak; output swing is rail-to-rail (0 V to VCC) with <2 V drop at 100 mA sink/source |
| VCC (Pin 5) | Driver supply / regulator output | Supplies driver core; also serves as regulated 11.5-V output when VDD is applied - powers external circuits within 20-mA limit |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 11.5-V series regulator | Enables direct use with 24-V or 36-V input rails while powering driver and external PWM controller from same node |
| BiCMOS output stage | Delivers 2-A peak current with <25-ns switching and <40-ns propagation, reducing MOSFET switching losses in >500-kHz converters |
| No active pullup input | Reduces quiescent current to <50 µA (VCC supply) and eliminates need for external biasing - ideal for low-power standby modes |
| High latch-up immunity | Rated per JEDEC JESD78; withstands transient overvoltage events common in motor drive and industrial power stages |
| –40°C to 125°C operation | Validated across full range with no derating - supports placement near hot power components in compact DC-DC modules |
Applications
| Industrial DC-DC Converters | Automotive Auxiliary Power Supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2817DBVT | Includes active pullup input circuit; 650-µA typical VCC supply current when IN = 0 V | Required when interfacing with open-collector PWM controllers (e.g., TL5001) without external pullup resistors | Select TPS2817DBVT only if active pullup is needed; otherwise TPS2819DBVT offers lower quiescent current and identical timing/regulation specs |
| TPS2829DBVR | Omits internal regulator and active pullup; quiescent current <15 µA; VDD pin unconnected (NC) | Suitable for fixed 5–14 V systems where external regulation is already present and ultra-low IQ is critical | Choose TPS2829DBVR for battery-powered or always-on systems; TPS2819DBVT preferred when 24–40 V input or regulated VCC is required |
Compared with TPS2817DBVT, TPS2819DBVT reduces input-stage current consumption by >90% in static conditions while retaining identical regulator performance and switching speed; versus TPS2829DBVR, it adds regulator functionality at the cost of slightly higher IQ but enables broader input voltage flexibility.

FAQ
What is the function of the VDD pin on the TPS2819DBVT?
The VDD pin on the TPS2819DBVT is the input to the internal series voltage regulator. When supplied with 8–40 V, it produces a regulated ~11.5-V output at the VCC pin, capable of sourcing up to 20 mA. This allows the TPS2819DBVT to power itself and external ICs (e.g., PWM controllers) from a single higher-voltage rail. Grounding VDD will destroy the regulator.
How does the TPS2819DBVT differ from the TPS2817DBVT?
The TPS2819DBVT and TPS2817DBVT share identical regulator, timing, and output specifications, but TPS2819DBVT omits the active pullup input circuit. As a result, TPS2819DBVT draws <50 µA (VCC) when inputs are static, versus ~650 µA for TPS2817DBVT at low input. Use TPS2819DBVT when interfacing with push-pull logic; choose TPS2817DBVT for open-collector controller compatibility.
Can the TPS2819DBVT drive both high-side and low-side N-channel MOSFETs?
The TPS2819DBVT is a noninverting driver with rail-to-rail output (0 V to VCC) and 2-A peak current, making it suitable for low-side N-MOSFET drive directly. For high-side N-MOSFET drive, it requires a floating supply (e.g., bootstrap capacitor or isolated DC-DC) referenced to the switch node - the TPS2819DBVT itself does not provide level-shifting or high-side gate bias generation.
What is the maximum capacitive load the TPS2819DBVT can drive while maintaining specified timing?
The TPS2819DBVT's 25-ns max rise/fall time and 40-ns max propagation delay are specified with a 1-nF capacitive load at VCC = 10 V. Performance degrades linearly with increasing load: at 2.2 nF, rise/fall times increase to ~30 ns (typical), and propagation delay extends to ~45 ns. Layout parasitics must be minimized - keep gate traces <2 inches and add 10-Ω series resistor near MOSFET gate if longer.
Is the TPS2819DBVT pin-compatible with other devices in the TPS28xx family?
Yes - all TPS28xx DBV-packaged variants (TPS2816/17/18/19/28/29) share identical 5-pin SOT-23 pinout: Pin 1 = VDD, Pin 2 = GND, Pin 3 = IN, Pin 4 = OUT, Pin 5 = VCC. However, functional differences exist: TPS2816/17 include active pullup; TPS2818/19 include regulator; TPS2828/29 omit both. Swapping requires verifying input logic and regulator requirements.
