Texas Instruments TPS2813PW

Overview

TPS2813PW from Texas Instruments is a dual-channel complementary MOSFET driver IC with one inverting and one noninverting output stage, 2-A peak source/sink current capability, 25-ns max rise/fall times (V_CC = 14 V, C_L = 1 nF), integrated 10–13-V regulator (REG_IN/REG_OUT), and −40°C to 125°C operating range. It drives high-side/low-side N-channel MOSFETs in synchronous buck converters and motor gate drivers.

For engineers reviewing the TPS2813PW datasheet, TPS2813PW pinout, TPS2813PW application, or TPS2813PW equivalent, key selection criteria include its complementary logic configuration, internal regulator enabling 14–40-V input operation, fast propagation delay (<40 ns), low 5-µA supply current, and TSSOP-8 package suitability for space-constrained power stages.

Technical Context

The TPS2813PW integrates two independent CMOS-input drivers - one inverting, one noninverting - sharing a common V_CC and GND, with separate 1IN and 2IN inputs driving 1OUT and 2OUT respectively. Its front-end Schmidt-trigger inputs provide 1.6-V hysteresis (V_CC = 5 V) and noise immunity, while the bipolar-MOSFET hybrid output stage ensures rail-to-rail swing (0.18 V low-level, 9.9 V high-level at 1 mA) and robust 2-A transient drive.

A dedicated linear regulator accepts 14–40 V on REG_IN and delivers 10–13 V at up to 20 mA on REG_OUT, allowing direct connection to high-voltage bus rails without external LDO. The regulator is optional: REG_IN and REG_OUT may be left open or tied to V_CC/GND when unused. Propagation delays (t_PLH/t_PHL) remain under 45 ns across 4–14 V V_CC, with rise/fall times tightly matched between channels (≤5 ns skew at no load).

FAQ

What logic configuration does the TPS2813PW implement?

The TPS2813PW implements a complementary dual-output configuration: Pin 2 (1IN) drives Pin 6 (1OUT) with inverting logic, while Pin 4 (2IN) drives Pin 8 (2OUT) with noninverting logic. This enables direct half-bridge gate drive without external inverters. Both channels share the same V_CC and GND, and their timing parameters (rise/fall, propagation delay) are tightly matched per datasheet Figure 23–24.

Can the TPS2813PW operate without using the internal regulator?

Yes - the TPS2813PW can operate with REG_IN and REG_OUT left unconnected when V_CC is supplied externally within 4–14 V. The regulator is optional: TI explicitly states REG_IN and REG_OUT "can be left disconnected or both connected to V_CC or GND" when not needed. In such cases, the device draws only 5 µA supply current from V_CC, maintaining full drive performance.

What is the maximum capacitive load the TPS2813PW can drive with specified timing?

The TPS2813PW's 25-ns max rise/fall time and 40-ns max propagation delay are specified with a 1-nF load at V_CC = 14 V. While it can drive larger loads (e.g., 10-nF shown in Figure 25–26), timing degrades: rise/fall times increase to ~60 ns and propagation delay exceeds 70 ns. For >2-nF loads, paralleling both outputs (per Figure 28–31) restores sub-30-ns edges, extending usable capacitance to ~5 nF per channel.

How does the TPS2813PW prevent shoot-through in bridge configurations?

The TPS2813PW minimizes shoot-through risk via three design features: (1) Schmidt-trigger inputs with 1.6-V hysteresis prevent oscillation during slow input transitions; (2) inherent output-stage architecture limits shoot-through current to <6 mA during input mid-rail biasing (Figures 17–18); and (3) matched channel timing (<5-ns skew) enables precise dead-time control in external logic. No external dead-time circuitry is required for typical half-bridge layouts.

Is the TPS2813PW pin-compatible with other TPS28xx variants in TSSOP-8?

Yes - all TPS28xx devices (TPS2811/12/13/14/15) use identical TSSOP-8 pinouts per datasheet Figures 1–3 and Terminal Functions table. Pin 1 (REG_IN), Pin 2 (1IN), Pin 3 (GND), etc., retain consistent functions across the family. However, logic configuration differs: TPS2813PW has complementary outputs, while TPS2812PW is dual noninverting and TPS2814PW implements dual AND gates - functional replacement requires verifying signal polarity and timing requirements.
