Infineon Technologies IR2136JTR

Overview

IR2136JTR 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 or IGBTs. It features +600V floating channel operation, 400ns/380ns typical turn-on/turn-off propagation delay, 3.3V logic compatibility, and integrated over-current shutdown with RCIN-programmable fault-clear delay. It is used in industrial motor inverters driving BLDC or PMSM motors.

For engineers reviewing the IR2136JTR datasheet, IR2136JTR pinout, IR2136JTR application, or IR2136JTR equivalent, key selection criteria include bootstrap-compatible high-side drive up to 600V, matched propagation delays across all six channels, undervoltage lockout thresholds (8.9V/8.2V), and external current-sense trip input with 0.46V threshold.

Technical Context

The IR2136JTR integrates proprietary HVIC technology for monolithic high-voltage isolation between low-side logic and floating high-side channels. Its level-shifted drivers support simultaneous 3-phase PWM control with built-in shoot-through prevention logic and programmable deadtime via external RC network on RCIN.

It implements independent UVLO monitoring per channel for both VCC (8.9V rising, 8.2V falling) and VBx supplies, plus an open-drain FAULT output that latches only during over-current events - cleared automatically after RCIN voltage exceeds 8V. Input noise filtering (200ns typical) and lower di/dt gate drive enhance EMI robustness in noisy motor-drive environments.

FAQ

What is the maximum allowable dV/dt on the VS pins of the IR2136JTR?

The IR2136JTR is rated for 50 V/ns dV/dt on its VS1–3 pins, verified per absolute maximum ratings. This immunity enables reliable operation when driving fast-switching SiC or GaN power stages where bus transients exceed 100 V/ns in unclamped conditions. The internal level-shifter design incorporates charge-pump stabilization and noise filtering to maintain logic integrity without external snubbers.

How does the ITRIP input function, and what external components are required?

The ITRIP pin accepts a voltage derived from a shunt resistor placed in the motor phase or DC-link return path. When voltage exceeds 0.46V (typical), it triggers immediate shutdown of all six outputs. No external comparator is needed - the internal comparator includes 70mV hysteresis. A simple RC low-pass filter (e.g., 100Ω + 1nF) is recommended to suppress switching noise, and blanking time is fixed at 150ns.

Can the IR2136JTR drive both MOSFETs and IGBTs, and what are the key layout considerations?

Yes - the IR2136JTR drives both N-channel MOSFETs and IGBTs via its 200mA source / 350mA sink outputs. Critical layout practices include separating COM and VSS ground planes, minimizing loop area for VBx–VSx bootstrap paths, using Kelvin connections for ITRIP, and placing 0.1µF + 10µF capacitors close to VCC and each VB pin. Thermal vias under the exposed pad (if present in SOIC-28W variant) are strongly advised.

Is the FAULT output latched, and how is fault recovery handled?

The FAULT output is not latched for undervoltage events - it returns to high-impedance once VCC or VBx recovers above UVLO thresholds. For over-current faults, FAULT remains low until the RCIN pin voltage exceeds 8V, which occurs after the externally programmed RC delay (e.g., 2ms with 2MΩ + 1nF). No external reset signal is required, enabling fully autonomous recovery in closed-loop motor systems.
