FEATURES  
DESCRIPTION  
300mA Continuous Output Current  
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.  
Low Side or High Side Switch  
Configuration  
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 avail-  
able 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.  
8V to 65V Operation  
Overload and Short Circuit Protection  
Power Interruption Protection  
+6V Regulated Voltage  
2mA Quiescent Current  
The input to the switch is driven by a low voltage signal, typically 5V. Addi-  
tionally, 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.  
Programmable Overcurrent and  
Power Interruption Protection  
1% to 30% Programmable Input  
Comparator Hysteresis (on UC37132)  
The device also has inherent smart features that allow for programmable  
turn-on delay in enabling the output following startup. The same capacitor  
that specifies the turn-on delay is also used to program a VCC power inter-  
ruption time. If VCC drops below a threshold for a time specified by this ca-  
pacitor, the output is turned off and a new turn-on delay will be re-triggered.  
Similarly, if high current persists longer than the response delay, the output  
driver will operate in a very low duty cycle mode to protect the IC.
