Infineon Technologies IR2136SPBF

Overview

IR2136SPBF from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with three independent half-bridge gate drivers for N-channel MOSFETs and IGBTs. It operates up to +600V offset voltage, features matched 400ns/380ns turn-on/turn-off propagation delays, undervoltage lockout on all channels, and over-current shutdown via external sense resistor. Used in industrial motor drives and inverters requiring robust bootstrap-based high-side drive.

For engineers reviewing the IR2136SPBF datasheet, IR2136SPBF pinout, IR2136SPBF application, or IR2136SPBF equivalent, key selection criteria include its 10–20V VCC supply range, 3.3V logic compatibility, programmable fault-clear delay via RCIN, cross-conduction prevention logic, and floating channel tolerance to negative dV/dt transients.

Technical Context

The IR2136SPBF integrates three independent HVIC-based floating channel drivers with level-shifted inputs, enabling simultaneous control of six power switches in 3-phase topologies. Its internal shoot-through prevention logic enforces deadtime between complementary HO/LO outputs per channel, and each high-side output is inverted relative to its HIN input.

It implements dual UVLO detection (VCC and VBx), a latched over-current shutdown triggered by ITRIP voltage ≥0.46V, and an open-drain FAULT signal that returns to high-impedance after automatic recovery when RCIN exceeds 8V. Propagation delays are tightly matched across all six outputs (±40ns max MDT), supporting high-frequency PWM up to 100 kHz.

Key Specifications

Pinout & Package

IR2136SPBF is supplied in a 28-lead SOIC package with wide creepage and reinforced isolation for high-voltage applications. Pin assignments follow industry-standard 3-phase driver layout with grouped high-side and low-side terminals, dedicated fault and enable signals, and separate bootstrap supply connections per phase.

FAQ

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

The IR2136SPBF is rated for 50 V/ns dV/dt at the VS1–VS3 pins. This specification ensures stable level-shifting operation during fast switching transitions in 600V bus applications. Exceeding this rate may cause false triggering of the high-side logic or temporary loss of gate drive, especially under light load or high-temperature conditions.

How does the ITRIP fault detection interact with the EN pin?

When ITRIP exceeds 0.46V, the FAULT signal asserts low and all six outputs shut down regardless of EN state. The EN pin remains functional during fault condition but cannot override the latched shutdown. Only RCIN-based auto-clear or power cycle restores operation-EN can only disable outputs preemptively, not recover from ITRIP fault.

Can IR2136SPBF drive both MOSFETs and IGBTs interchangeably?

Yes-the IR2136SPBF is designed for both N-channel MOSFETs and IGBTs. Its 200mA/350mA pulsed output current and 12–20V VBS range accommodate typical gate charge requirements of 600V-class devices. However, IGBTs with high tail current may require external snubbers due to lack of active Miller clamping in this driver.

What is the minimum pulse width required for reliable HIN input recognition?

The IR2136SPBF requires a minimum HIN pulse width of 1 µs for reliable high-side PWM recognition, as specified in the dynamic electrical characteristics table. Shorter pulses may fail to propagate through internal noise filters and deadtime logic, resulting in missed switching events or inconsistent output behavior at high PWM frequencies.
