BD2270HFV-TR ROHM

Datasheet Controller ICs for High Side NMOSFET BD2270HFV General Description Key Specifications BD2270HFV is a gate driver for high side -CNhannel Input Voltage Range: 2.7V to 5.5V MOSFET that comes with a discharge circuit for the GATE Rise Time (C = 500pF): 130s (Typ) GATE output capacitive load. An internal charge pump GATE Output Voltage(V = 5V): 13.5V(Typ) CC enables the IC to drive the gate of an external high Operating Current: 50A(Typ) side NMOSFET without using any external parts. The Standby Current: 5A (Typ) power up sequence is controlled by a comparator with Operating Temperature Range: -25C to +85C hysteresis function. The space saving HVSOF5 package is used.
