Infineon Technologies AUIRS2113STR

Overview

AUIRS2113STR from Infineon Technologies (formerly International Rectifier) is an automotive-grade high- and low-side gate driver IC designed to independently control N-channel MOSFETs or IGBTs in half-bridge configurations. It supports up to 600 V offset voltage, delivers ±2.5 A peak output current per channel, features matched propagation delays ≤35 ns, and operates with 3.3 V–20 V logic supply and 10 V–20 V gate drive supply - used in HEV traction inverters and automotive DC/DC converters.

For engineers reviewing the AUIRS2113STR datasheet, AUIRS2113STR pinout, AUIRS2113STR application, or AUIRS2113STR equivalent, key selection criteria include its 600 V floating channel rating, cycle-by-cycle shutdown logic, dV/dt immune design, CMOS Schmitt-triggered inputs, and AEC-Q100 qualification for under-hood motor control systems.

Technical Context

The AUIRS2113STR integrates two independent HVIC channels: a high-side driver referenced to a floating VS node (rated to +600 V) and a low-side driver referenced to COM. Its latch-immune CMOS architecture enables robust operation during fast transient events, with logic inputs tolerant to ±5 V ground offset between VSS and COM.

Propagation delay matching (≤35 ns max) and in-phase output response simplify PWM timing in high-frequency bridge topologies. Undervoltage lockout (UVLO) is implemented separately on VBS (7.0–9.7 V threshold) and VCC (7.0–9.6 V), ensuring safe turn-off during supply droop.

FAQ

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

The AUIRS2113STR is rated for 50 V/ns dV/dt at the VS pin under all operating conditions. This specification is validated per AEC-Q100 test methods and ensures reliable operation during fast-switching events in 600 V bridge circuits without false triggering or latch-up.

Does the AUIRS2113STR require external bootstrap diodes and capacitors?

Yes - the AUIRS2113STR requires an external bootstrap diode and capacitor connected between V_BS and V_S to maintain high-side gate drive voltage during continuous high-side conduction. The recommended diode is ultrafast (t_rr < 35 ns), and capacitor value is typically 0.1–0.22 µF X7R ceramic.

Can HIN and LIN be driven with complementary PWM signals without external dead-time insertion?

No - the AUIRS2113STR does not include internal dead-time generation. Complementary PWM signals must include externally generated dead time (≥300 ns typical) to prevent shoot-through, as the device propagates inputs directly to outputs with matched but non-zero delays.

Is the SD pin compatible with open-drain MCU outputs?

Yes - the SD pin is active-low and internally pulled up to V_DD. It accepts standard 3.3 V or 5 V open-drain MCU outputs without external pull-up resistors, and triggers cycle-by-cycle shutdown within 220 ns of signal assertion.
