Diodes Incorporated AP22980 6V/6A Low RON Power Switch

Diodes Inc. AP22980 6V/6A Low RON Power Switch is a single-channel high-side power switch with slew rate control, tri-state soft-start, and active output discharge path in a compact size. The AP22980 contains an N-channel MOSFET that supports 6A of maximum continuous current and operates over an input range of 0.285V to 5.5V. The wide input voltage range and high current capability enable the device to be used in various systems and applications. The AP22980 has ultra-low ON-resistance of typical 5.1mΩ, which can minimize the voltage drop and power loss.

A low quiescent supply current of 60µA (typ.) makes it ideal for a system where standby power consumption is a concern. The AP22980 offers multiple VOUT slew rates by tri-state logic input of SS pin, which does not require an external component. The AP22980 has a 50Ω on-chip resistor for quick output discharge when the switch is disabled to avoid an unknown state caused by floating condition to downstream load. Overtemperature protection circuitry is triggered if the junction temperature exceeds +150°C, thereby protecting the AP22980 and downstream circuit from potential damage. The Diodes Inc. AP22980 is available in a compact W-QFN1520-10 package.
