Texas Instruments TPS2819DBVR

Overview

TPS2819DBVR from Texas Instruments is a noninverting single-channel high-speed MOSFET driver with internal voltage regulator, delivering up to 2-A peak output current, 25-ns max rise/fall times (1-nF load), and 40-ns max propagation delay. It operates from 4-V to 14-V VCC supply, supports regulator input up to 40 V (VDD), and is housed in a 5-pin SOT-23 (DBV) package for high-frequency DC/DC converter gate drive.

For engineers reviewing the TPS2819DBVR datasheet, TPS2819DBVR pinout, TPS2819DBVR application, or TPS2819DBVR equivalent, key selection criteria include regulated VCC generation capability, CMOS-input logic compatibility (no active pullup), low quiescent current (25–50 µA), and operation across –40°C to 125°C ambient temperature.

Technical Context

The TPS2819DBVR implements a BiCMOS output stage for high instantaneous drive current and rail-to-rail low-drop switching, minimizing shoot-through via inherent design. Its input stage uses standard CMOS thresholds (≈2/3 VCC for positive-going, ≈1/3 VCC for negative-going) with 1.3-V hysteresis and <0.2-µA input leakage.

The integrated series regulator accepts VDD input from 8 V to 40 V and delivers a stable 10–13-V output (typ 11.5 V) at up to 20 mA, enabling self-powered operation and external circuit biasing - provided total power dissipation remains within the 437-mW DBV package limit at TA ≤ 25°C.

FAQ

What is the function of the VDD pin on the TPS2819DBVR?

The VDD pin on the TPS2819DBVR is the input to the internal series regulator. When supplied with 8 V to 40 V, it generates a regulated 10–13 V output on the VCC pin, powering both the driver core and optionally external circuitry. If the regulator is unused, VDD must be tied to VCC - grounding VDD will destroy the regulator.

Does the TPS2819DBVR have an active pullup circuit on its input?

No, the TPS2819DBVR does not include an active pullup circuit on its IN pin. Unlike TPS2816/TPS2817, it features standard CMOS inputs with <0.2 µA leakage at logic high or low, making it ideal for direct interface with CMOS microcontrollers and low-power PWM controllers without external biasing.

What is the maximum continuous output current rating for the TPS2819DBVR?

The TPS2819DBVR is rated for ±100 mA continuous output current at the OUT pin. Its 2-A peak current capability applies only to transient gate-charge pulses (e.g., charging MOSFET Ciss), not steady-state loads. Exceeding ±100 mA continuously risks thermal shutdown or damage due to package power limits.

Can the TPS2819DBVR operate with a 5-V supply?

Yes, the TPS2819DBVR operates with a 5-V VCC supply within its 4-V to 14-V range. At VCC = 5 V, input thresholds are approximately 3.3 V (rising) and 1.7 V (falling), and rise/fall times increase to ~35 ns (1-nF load). The internal regulator remains functional only if VDD ≥ 8 V.

What is the thermal dissipation limit of the TPS2819DBVR in SOT-23 (DBV) package?

The TPS2819DBVR in the 5-pin SOT-23 (DBV) package has a maximum power dissipation of 437 mW at TA ≤ 25°C, derating linearly at 3.5 mW/°C above that temperature. At TA = 70°C, usable power drops to 280 mW; proper PCB copper area and thermal vias are essential for sustained 2-A peak drive at elevated temperatures.
