Diodes, Inc. Announces Single Channel Smart Load Switch for Battery Powered Portable Applications
Diodes Inc. announced the release of its AP2280 single channel smart load switch. The AP2280 supports high-side load current switching up to 2A in 1.8 to 5V systems and is targeted for use in sophisticated electronic devices such as notebook PCs, Bluetooth headsets, mobile and smart phones, portable GPS navigation devices, portable audio players and digital cameras.
Offered in a compact 2 x 1.8mm leadless DFN package, Diodes’ single channel slew rate controlled smart load switch with best-in-class low quiescent and shutdown current, is designed to extend battery life in a wide range of portable electronic applications while occupying minimal PCB real estate.
The AP2280 features a single P-channel MOSFET power switch with a typical RDS(0N) of 80mΩ at 5V allowing high load current handling capability, while conserving battery life. The integration of slew rate control circuitry controls in-rush current spikes from disrupting the supply rail and causing glitches when turning on sensitive ICs such as microprocessors and DSPs. The 1.8 to 6V operating voltage makes AP2280 well suited to support single cell lithium battery and 2-3 cell MiMH/NiCad /Alkaline battery applications.
"The introduction of AP2280 demonstrates Diodes’ commitment to expand our analog power management products into the fast growing portable and battery powered product segment," said Mark King, Senior VP Sales and Marketing of Diodes, Inc. "This device, with industry leading low quiescent current and offered in our low-profile leadless DFN package, offers clear performance advantages with both power and PCB space savings."
The AP2280 load switch is offered in a small and low profile DFN2018-6 package, making it suitable for integration into thin and compact applications where space and height are critical design considerations. Also offered in SOT-25, the AP2280 offers designers two factory programmed turn-on rise time options of 100µs or 1ms, include an Enable pin, and feature a fast discharge pin (DIS) option to discharge parasitic inductance which can further increase system reliability. This new device is fully RoHS compliant, including Green Molding compound. The AP2280 load switch supports an industrial temperature range of -40 to +85°C.
