Product details

Overview

TPS2811P from Texas Instruments is a dual inverting high-speed MOSFET driver IC with integrated regulator, delivering 2-A peak output current per channel into 1-nF loads at VCC = 14 V, featuring ≤25-ns rise/fall times and ≤40-ns propagation delay. It operates across −40°C to 125°C and supports 4-V to 14-V supply voltage (with internal regulator extending input range to 40 V), used in synchronous buck converters and high-frequency power stage gate driving.

For engineers reviewing the TPS2811P datasheet, TPS2811P pinout, TPS2811P application, or TPS2811P equivalent, this page delivers verified technical context, exact pin functions, real-world switching performance under load, regulator interface behavior, and validated alternative options for industrial DC-DC and motor drive designs.

Technical Context

The TPS2811P integrates two independent inverting CMOS drivers with Schmidt-trigger inputs (V_TH+ ≈ 2/3 VCC, V_TH− ≈ 1/3 VCC) and a linear regulator (REG_IN → REG_OUT) that outputs 10–13 V at up to 20 mA. Its bipolar-MOSFET hybrid output stage enables rail-to-rail swing (0.18 V low-level, 9.9 V high-level at 10 V VCC) while sustaining 2-A instantaneous source/sink capability.

It uses a shoot-through-minimized architecture limiting cross-conduction to <6 mA during input transitions, and its propagation delay remains stable across temperature (−40°C to 125°C) and supply voltage (4–14 V), with no dependency on input slew rate due to internal predrive isolation.

Key Specifications

Parameter	Value and Actual Design Meaning
Rise/Fall Time	≤25 ns / ≤25 ns (CL = 1 nF, VCC = 14 V): ensures sub-40-ns edge control for >10 MHz switching in synchronous rectifiers.
Propagation Delay	≤40 ns max (high-to-low & low-to-high, CL = 1 nF, VCC = 14 V): enables precise timing alignment between complementary high-side/low-side gate signals.
Peak Output Current	2 A per channel (VCC = 14 V): sufficient to drive Hex-3 MOSFETs (e.g., IRF530) with <20-ns turn-on under clamped inductive load.
Supply Voltage Range	4 V to 14 V (VCC); REG_IN supports 8–40 V: allows direct connection to 12-V or 24-V bus while regulating VCC to safe 11.5-V nominal for gate drive stability.
Input Threshold Hysteresis	≈1.2–1.6 V (VCC = 5–14 V): provides noise immunity against EMI in noisy power-converter environments without external Schmitt triggers.
Quiescent Supply Current	5 µA max (VCC inputs high/low): enables ultra-low standby power in battery-backed or always-on industrial controllers.
Operating Temperature	−40°C to 125°C ambient: qualified for under-hood automotive DC-DC, industrial PLC I/O modules, and telecom power supplies.

Pinout & Package

TPS2811P is supplied in an 8-pin plastic DIP (dual in-line package) with through-hole mounting and 0.3-inch body width. Pin spacing is 0.1 inch, lead finish is matte tin, and thermal resistance θ_JA is 115°C/W.

Pin/Terminal	Circuit Role	Design Meaning
1 - REG_IN	Regulator input	Accepts 8–40 V unregulated input; powers internal LDO to generate stable VCC-regulated supply for driver core.
2 - 1IN	Inverting input 1	CMOS-compatible digital input; drives 1OUT inverted (active-low logic: high IN → low OUT).
3 - GND	Power and signal ground	Common reference for VCC, REG_OUT, inputs, and outputs; must be low-inductance connection to minimize ground bounce.
4 - 2IN	Inverting input 2	Independent CMOS input for second channel; identical threshold and hysteresis to 1IN.
5 - 2OUT	Output 2	Inverted output corresponding to 2IN; capable of 2-A peak sink/source into capacitive gate loads.
6 - VCC	Driver supply voltage	Primary power rail for output stage; regulated by internal LDO when REG_IN is active, or directly powered if REG_IN unused.
7 - 1OUT	Output 1	Inverted output corresponding to 1IN; electrically identical to 2OUT with matched propagation delay (<1 ns skew).
8 - REG_OUT	Regulator output	10–13 V regulated output (20 mA max); can power auxiliary circuitry (e.g., level shifters, bias networks) if within thermal limits.

Key Features

Feature	Design Value
Dual inverting logic	Enables direct drive of N-channel high-side + low-side MOSFET pairs in half-bridge topologies without external inverters.
Bipolar-MOSFET hybrid output	Guarantees full rail-to-rail swing (0.18 V low, 9.9 V high @ 10 V VCC), ensuring reliable turn-off of low-threshold MOSFETs (e.g., logic-level devices).
Integrated 40-V tolerant regulator	Allows single-supply operation from 24-V or 36-V industrial buses while maintaining safe 11.5-V VCC for consistent gate drive strength and timing.
Shoot-through current limit	Restricts cross-conduction to <6 mA during input transitions-critical for preventing destructive shoot-through in bridge circuits.
Input hysteresis & high-Z CMOS	1.2–1.6 V hysteresis + ~1 GΩ input impedance rejects noise and eliminates need for external pull-ups in open-drain control interfaces.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual inverting MOSFET driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS2811DR	Same silicon, SOIC-8 package (vs. PDIP-8); 520-mW power rating (vs. 1090 mW); θ_JA = 145°C/W (vs. 115°C/W).	Preferred for space-constrained PCBs with reflow assembly; unsuitable for high-power dissipation (>700 mW) without heatsinking.	Select TPS2811DR only when board area and automated assembly outweigh thermal derating requirements.
UCC27424D	Noninverting dual driver (not inverting); 4-A peak current; no integrated regulator; 4.5–15-V VDD range; 15-ns typical rise time.	Requires external inversion logic for half-bridge use; better suited for high-current, regulator-free designs where layout allows separate VDD regulation.	Choose UCC27424D when peak current >2 A is mandatory and system already provides clean 12-V gate supply-avoid if regulator integration is needed.

Compared with TPS2811P, TPS2811DR offers identical electrical performance in a smaller footprint but sacrifices 35% thermal margin, while UCC27424D trades regulator integration and inverting logic for higher peak current and faster edges-making it suitable only when external regulation and signal inversion are acceptable.

FAQ

What is the function of the REG_IN and REG_OUT pins on the TPS2811P?

The REG_IN pin accepts an unregulated input voltage from 8 V to 40 V and feeds Texas Instruments' internal linear regulator, which produces a stable 10–13 V output at REG_OUT (up to 20 mA). This allows the TPS2811P to operate safely from higher bus voltages while maintaining optimal VCC for consistent gate drive strength and timing. When unused, both REG_IN and REG_OUT may be left floating or tied to VCC/GND.

Can the TPS2811P drive both high-side and low-side N-channel MOSFETs in a half-bridge configuration?

Yes-the TPS2811P's dual inverting outputs enable direct half-bridge drive: one channel controls the low-side MOSFET (1IN high → 1OUT low), while the other drives the high-side MOSFET through a level shifter or bootstrap circuit (2IN high → 2OUT low, enabling gate turn-on relative to source potential). Its rail-to-rail output swing ensures reliable turn-off of logic-level MOSFETs.

What is the maximum capacitive load the TPS2811P can drive while maintaining specified rise/fall times?

The TPS2811P maintains ≤25-ns rise/fall times with a 1-nF load at VCC = 14 V, as characterized in the SLVS132F datasheet. For larger loads (e.g., 10 nF), rise/fall times increase to ~50 ns, but the device remains functional. To preserve speed, TI recommends paralleling both outputs (1OUT + 2OUT) for loads >2 nF-verified to improve edge rates by 30% in application testing.

Does the TPS2811P require external decoupling capacitors, and if so, what values are recommended?

Yes-TI specifies a 0.1-µF ceramic capacitor between VCC and GND, placed as close as possible to the TPS2811P pins, to supply instantaneous current during fast switching. For the regulator, a 0.1-µF ceramic capacitor is required between REG_OUT and GND for stability, plus a 4.7-µF electrolytic capacitor for improved transient response when sourcing >5 mA from REG_OUT.

How does the TPS2811P prevent shoot-through current during input transitions?

The TPS2811P minimizes shoot-through via an internal architecture that inherently limits cross-conduction to <6 mA during input transitions-even when inputs are biased near VCC/2. This is achieved through controlled predrive staging and bipolar-MOSFET output topology, eliminating the need for external dead-time control in many half-bridge implementations using the TPS2811P.
