MIC2039
Overview
The MIC2039 is a high-side MOSFET power distribution switch providing increased system reliability by using 5% current-limit accuracy. The MIC2039 has an operating input voltage range from 2.5V to 5.5V, is internally current limited, and has thermal shutdown to protect the device and system.
- ±5% current limit accuracy
- Input supply range from 2.5V to 5.5V
- Low quiescent current: 100µA typical (switch ON)
- 75mΩ typical RDS(ON) at 5.0V
- 0.2A to 2.5A adjustable output current
- Kickstart - momentary secondary current-limit threshold (120ms period)
- Soft-start functionality
- Undervoltage lockout (UVLO)
- Fast 10µs short-circuit response time (non-Kickstart options)
- Fault status output flag
