R5560Z Series High-Current/Overvoltage Protection Switch IC with Voltage Suppressor No. EA-328-170517 OUTLINE The R5560Z is a CMOS-based high-current and overvoltage protection switch IC with voltage suppressor that uses an NMOS pass transistor to achieve ultra-low on resistance (Typ. 38 m). The R5560Z consists of a soft-start circuit, a startup debounce circuit, an overvoltage lockout (OVLO) circuit, and a thermal shutdown circuit. The OVLO threshold is adjustable with optional external resistors to any voltage between 4 V and 20 V. The internal OVLO threshold (preset to 6.8 V 3%) is available when connecting the OVLO pin to GND. An internal clamp can protect low-voltage systems from surges up to +80 V (The surge waveform is compliant with IEC 61000-4-5 Combination Wave.) without using a transient-voltage-suppression (TVS) diode. The R5560Z is offered in a small and thin WLCSP-12-P2 (1.288 mm x 1.828 mm) package which achieves the smallest possible footprint solution on boards where area is limited.
