1ch Gate Driver Providing Galvanic Isolation

2500Vrms Isolation Voltage

BM60055FV-C

General Description

The BM60055FV-C is a gate driver with an isolation

voltage of 2500Vrms, I/O delay time of 250ns, minimum

input pulse width of 170ns. It incorporates the fault signal

output function (FLT_UVLO, FLT_SC, FLT_OT), under

voltage lockout (UVLO) function, short circuit protection

(SCP) function, over temperature protection (OT)

function, over current protection (OC) function, Soft turn

off function, 2 level turn off function, active miller

clamping function, switching controller function and

output state feedback function.
