1ch Gate Driver Providing Galvanic Isolation
2500Vrms Isolation Voltage
BM60055FV-C
General Description
Key Specifications
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.
