Description

General part information

UC27131 Series

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.

The input to the switch is driven by a low voltage signal, typically 5V. Additionally, UC37132 features adjustable hysteresis. The output of the device can switch a load between 8V and 65V. Output current capability is 300mA continuous or 700mA peak.
