Three-Level Configurable Slew-Rate Controlled Power Switch from Diodes Incorporated Simplifies and Enhances Power-Rail Management in Solid State Drives

2022-12-16 | 返回

Diodes Incorporated (Diodes) has introduced a new versatile single-channel high-side power switch. The DIODES™ AP22980 features three different selectable slew rates, so that wider capacitance loads can be handled while keeping inrush currents down, ensuring system stability. This 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 5.1mΩ enabling loads reaching 6A 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 0.285V to 5.5V - enabling greater application flexibility.

With 60µA (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 three-level selectable slew rate power switches are supplied in the compact W-QFN1520 package that takes up little board space and eases integration. These devices are available at $0.27 in 1000 piece quantities.
