LT1970ACFE#PBF

LT®1970A 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 1% 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. Typical applications include automatic test equipment, laboratory power supplies, motor drivers, thermoelectric cooler driver.

• Independent adjustment of source and sink current limits
• 1% current limit accuracy
• Improved reactive load driving stability
• 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 and 3.6MHz gain-bandwidth product
• 20 lead TSSOP package
• Operating temperature range from 0°C to 70°C
