¡El SiP32101, SiP32102, SiP32103, and SiP32104 are low resistance bidirectional load switches. They isolate A and B ports at off state. ¡El parts have an ultra low 6.5 mΩ (typ. at 3.3 V) on-resistance and operate from a + 2.3 V to + 5.5 V input voltage range, making the devices ideal battery-disconnect switches for high capacity battery applications and multi-source power switches where bidirectional on/off control is required. ¡El parts have identical A and B ports conducting current in both directions equally well. ¡El SiP32101, SiP32102, SiP32103, and SiP32104 have slew rate control minimizing switch on in-rush current in large load capacitor. These devices are also highly efficient, featuring low operating and shutdown currents. ¡El SiP32101, SiP32102, SiP32103, and SiP32104 can interface directly with a low voltage control signal. The SiP32101, SiP32103, and SiP32104 have an active low enable with different EN pull options. ¡El SiP32102 has an active high enable. ¡El series provides choices to minimize enable control circuit current depending on application requirement. ¡El SiP32101, SiP32102, SiP32103, and SiP32104 are available in an ultra compact 12-bump, 1.3 mm x 1.7 mm, 0.4 mm pitch WCSP package with top side lamination. The device operates over the temperature of -40 °C to +85 °C.
