±500mA Minimum Output Current Independent Adjustment of Source and Sink Current Limits 2% Current Limit Accuracy Operates with Single or Split Supplies Shutdown/Enable Control Input Open Collector Status Flags: Sink Current Limit Source Current Limit Thermal Shutdown Fail Safe Current Limit and Thermal Shutdown 1.6V/µs Slew Rate 3.6MHz Gain Bandwidth Product Fast Current Limit Response: 2MHz Bandwidth Specified Temperature Range: ­ 40°C to 85°C Available in a 20-Lead TSSOP Package
The LT®1970 is a ±500mA power op amp with precise externally controlled current limiting.

Separate control voltages program the sourcing and sinking current limit sense thresholds with 2% accuracy. Output current may be boosted by adding external power transistors. The circuit operates with single or split power supplies from 5V to 36V total supply voltage. In normal operation, the input stage supplies and t
