JSMSEMI AGD8136A-JSM

AGD8136A is an N-type high-voltage, high-speed power MOSFET/IGBT high- and low-side three-phase gate driver IC, incorporating three independent half-bridge drive circuits. Integrated undervoltage lockout (UVLO) and overcurrent protection shut down all six channel outputs immediately upon fault detection. An external enable control is provided to simultaneously disable all six channel outputs. Overcurrent faults are automatically cleared after an externally programmable delay set by an RC network connected to the RCIN input. Logic inputs are compatible with CMOS or LSTTL logic output levels as low as 3.3V, with a maximum floating channel operating voltage of 700V. Suitable for driving N-channel high-voltage power MOSFETs/IGBTs and similar devices. The AGD8136A is available in a SOP-28-300mil package and operates over a temperature range of -40 to 125℃.

Three high-side floating drivers operate in systems above 700V via bootstrap circuitry, enabling 100% duty cycle operation when the VB–VS voltage exceeds the undervoltage threshold.

The AGD8136A input stage integrates a filtering function: when the input signal exhibits jitter or the input pulse width is shorter than the filter time, the output signal remains unchanged. Inputs are compatible with both CMOS and TTL, facilitating easy connection to host controller ICs.

The AGD8136A incorporates multiple protection features, including EN enable control, internal interlocking, and overcurrent detection. When the EN pin is driven low, the driver will not trigger any output under any condition. The internal interlock prevents simultaneous high-level signals on both HO and LO outputs, eliminating shoot-through in bridge circuit power stages. Overcurrent detection rapidly monitors current changes in power devices, ensuring stable operation.

Additionally, to meet diverse industrial design requirements, the AGD8136A features an adjustable-delay restart port. By selecting appropriate RC network parameters, the restart time can be freely configured within a defined range.
