General Description
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. The MIC2039 is offered with either active-high or active-low logic level enable input controls. It has an open drain fault status output flag with a built-in 32ms delay that asserts low during overcurrent or thermal-shutdown conditions.

• ±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
• Logic-controlled enable (active-high, active-low)
• Thermal shutdown
• Pin compatible with the MIC2009/MIC2019
• 6-pin 2mm × 2mm thin DFN and 6-pin SOT-23 packages
• Junction temperature range from −40°C to +125°C

• USB peripherals and USB 2.0/3.0 compatible
• Notebooks and consumer electronics
• General-purpose power distribution
