智能功率开关 Smart Power Switch
DESCRIPON
The UC37131, UC37132 and UC37133 are a family of smart power switches which can drive resistive or inductive loads from the high side or low side.
The UC37132 is available in 14 pin DIP, 16 pin SOIC, or 20 pin CLCC packages and can accommodate both low side load to VCC or high side load to GND configurations. The UC37131 and UC37133 are exclusively for a low side or a high side configuration respectively and both are available in an 8 pin package. Both high side and low side configurations provide high current switching with low saturation voltages which can drive resistive or inductive loads.
