STMicroelectronics SRK1004
SRK1004 is disabled Internally regulated supply voltage of the device. The totem-pole output stage intended to drive N-channel power MOSFETs is powered from 5 GD the regulated supply voltage available on pin 4 (VCC). The pin is to be connected directly to the SR MOSFET gate terminal 6 DVS Drain voltage sensing.FEATURES
