Product details

Overview

AUIRS2012STR from Infineon Technologies (formerly International Rectifier) is an automotive-grade high- and low-side gate driver IC designed for bootstrap-based half-bridge control in DC-DC converters. It delivers 2 A source/sink current, operates up to 200 V VS offset, supports 10–20 V supply range, features matched 60 ns typical propagation delays, and is qualified per AEC-Q100 for use in mild hybrid vehicle power stages.

For engineers reviewing the AUIRS2012STR datasheet, AUIRS2012STR pinout, AUIRS2012STR application, or AUIRS2012STR equivalent, key selection criteria include VS withstand capability, propagation delay matching (<20 ns max), CMOS/Schmitt-trigger input compatibility, under-voltage lockout thresholds (VCCUV+ = 6–8 V), and SOIC-8N thermal resistance (100 °C/W).

Technical Context

The AUIRS2012STR integrates independent high-side and low-side drivers with floating channel architecture enabling bootstrap operation up to 200 V VS potential. Its dual-channel design maintains in-phase output response to HIN/LIN inputs and includes dedicated UVLO on both VCC and VB supplies with 1 V hysteresis.

It employs CMOS Schmitt-triggered inputs for noise immunity, supports switching frequencies up to 400 kHz, and guarantees matched turn-on/turn-off delay (≤20 ns max mismatch) across channels-critical for minimizing shoot-through risk in synchronous buck or multiphase topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
VS-MAX	200 V - maximum floating offset voltage sustainable without breakdown
I_O+/I_O−	2 A - peak gate drive current enables fast MOSFET switching in ≤100 ns
t_ON/t_OFF	60 ns (typ) - ensures tight timing control in high-frequency DC-DC stages
Delay Matching	20 ns (max) - limits channel-to-channel skew to prevent overlap conduction
V_CC Range	10–20 V - accommodates wide-input automotive supply rails including transients
UVLO Thresholds	VCCUV+ = 6–8 V, VBSUV+ = 6–8 V - prevents erratic operation during brown-out
R_thJA	100 °C/W - defines thermal derating limit under standard board-mount conditions

Equivalent & Alternatives

The following parts are listed as comparable options for similar high- and low-side gate driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRS2007STRPBF	Lower VS-MAX (100 V), no VBS UVLO, same SOIC-8N package	Restricted to ≤100 V half-bridge topologies; unsuitable for 200 V mild hybrid nodes	Select only when VS stress remains below 100 V and UVLO redundancy is not required
UCC27211D	Higher I_O (4 A), no integrated bootstrap diode path, requires external VB decoupling	Better suited for high-current GaN FETs but adds layout complexity for bootstrap stability	Prefer when >2 A drive or faster edge rates are needed, and board space allows external components

Compared with IRS2007STRPBF and UCC27211D, the AUIRS2012STR uniquely balances 200 V robustness, automotive qualification, dual UVLO, and matched timing-making it optimal for cost-sensitive, safety-critical 48 V system power stages where layout simplicity and transient resilience are prioritized.

FAQ

What is the maximum allowable dV/dt at the VS pin?

The AUIRS2012STR specifies a maximum allowable dVS/dt of 50 V/ns. This rating ensures reliable operation during fast-switching events in high-frequency DC-DC converters, preventing false triggering or latch-up in the floating high-side channel under transient voltage stress.

Does the AUIRS2012STR integrate bootstrap diode functionality?

No, the AUIRS2012STR does not integrate a bootstrap diode. It requires an external fast-recovery diode (e.g., 1N4148 or equivalent) between VCC and VB to charge the bootstrap capacitor during low-side conduction. The VB pin is solely a supply input terminal, not a diode-anode connection.

Can HIN and LIN be driven independently to implement non-overlapping gate timing?

Yes-HIN and LIN accept independent logic inputs and drive HO and LO outputs in phase with their respective signals. However, the device provides no built-in dead-time generation; external timing control (e.g., MCU PWM with programmable dead time) is required to prevent shoot-through in half-bridge configurations.

What is the minimum recommended bootstrap capacitor value for 400 kHz operation?

For 400 kHz switching with 50% duty cycle, a minimum 100 nF ceramic capacitor (X7R, 25 V rated) is recommended between VB and VS. This ensures sufficient charge replenishment per cycle while maintaining <100 mV ripple on the VB rail under 2 A peak load and typical PCB parasitics.
