ONSEMI FPF1321BUCX Dual Power Switch
The FPF1320 and FPF1321 are advanced dual-input, single-output power switches designed for portable devices. They feature low on-resistance, slew-rate-controlled turn-on to prevent inrush current, and support seamless transitions between power sources with break-before-make operation. These devices operate over 1.5V to 5.5V input range, include true reverse-current blocking, and have a quick discharge feature on the FPF1321 model. Compact wafer-level chip-scale packages ensure easy integration into mobile and NFC-enabled applications, offering robust safety and efficiency in power management.
