On-Bright Electronics OB2136

OB2136 is a monolithic three-phase half-bridge gate driver IC designed for high voltage, high speed, driving MOSFETs and IGBTs operating up to 650V. The protection functions include over temperature protection, under voltage lockout, inter-lock function and inverter over current trip with an automatic fault-clear function.

GENERAL DESCRIPTION

OB2136 uses high voltage process and common mode noise canceling technique provides stable operation of high-side drivers under high dV/dt noise circumstance. Over current protection that terminates all six outputs can be derived from an external current sense resistor. An open drain fault signal is provided to indicate that over current or over temperature or under voltage shutdown has occurred. The UVLO circuits prevent malfunction when Vcc or Vbs are lower than the threshold voltage. An enable function is available to shutdown all six outputs. Output drivers source and sink 600mA and 900mA at least, respectively, which is suitable for threephase inverter application in motor driver systems.
