Smart Power Switch

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.
