FAN7382

The FAN7382, a monolithic half-bridge gate driver IC, can drive MOSFETs and IGBTs that operate up to +600V. Fairchild's high-voltage process and common-mode noise canceling technique provides stable operation of the high-side driver under high dv/dt noise circumstances. An advanced level shift circuit allows high-side gate driver operation up to VS = -9.8 V (typ.) for VBS = 15V. The input logic level is compatible with standard TTL-series logic gates. UVLO circuits for both channels prevent malfunction when VCC and VBS are lower than the specified threshold voltage. Output drivers typically source/sink 350mA/650mA, respectively, which is suitable for fluorescent lamp ballasts, PDP scan drivers, motor controls, etc.

The FAN7382 is designed as one kind of monolithic half-bridge gate driver IC that can be used in fluorescent lamp ballast and PDP scan driver. Features of the FAN7382 are:(1)floating cannel designed for bootstrap operation to +600V.; (2)typically 350mA/650mA sourcing/sinking current driving capability for both channels; (3)common-mode dv/dt noise canceling circuit; (4)extended allowable negative VS swing to -9V for signal propagation @ Vcc=VBS=15V; (5)Vcc & VBS supply range from 10V to 20V; (6)UVLO functions for both channels; (7)TTL compatible input logic threshold levels; (8)matched propagation delay below 50nsec; (9)output in-phase with input.
