Power switch offers three different selectable slew rates
Diodes Incorporated has introduced the AP22980, a new versatile single-channel high-side power switch. The power switch features three different selectable slew rates, so that wider capacitance loads can be handled while keeping inrush currents down, ensuring system stability. The power switch is targeted at the solid-state data storage systems used in portable electronic equipment, computer hardware, and edge-based data center deployments.
The N-channel MOSFET, with a built-in charge pump inside the AP22980, has an extremely low Rds(ON) of 5.1 mΩ enabling loads reaching 6 A while minimizing voltage drops and power losses in high current loading applications. By having a separate VBIAS pin, the minimum input voltage that it is capable of supporting is significantly lower, resulting in a wider input voltage range that can be covered — from 0.285 V to 5.5 V — enabling greater application flexibility.
With 60 µA (typical) quiescent supply current, the AP22980 is highly optimized for situations where keeping standby power consumption down is a priority. This device has an operational temperature range of -40°C to 105°C. If the junction temperature exceeds 150°C, an overtemperature protection mechanism is triggered.
The AP22980 power switch has 50 Ω on-chip resistor for quick output discharge when switch is disabled to avoid unknown state caused by floating condition to downstream load.
The AP22980 three-level selectable slew rate power switches are supplied in the compact W-QFN1520 package that takes up little board space and eases integration.
