Overvoltage Protector IC with Reverse Current Protection
The R5528Z001A is a CMOS-based overvoltage protector IC with reverse current protection that use an NMOS pass transistor to achieve ultra-low on resistance (Typ. 54mΩ). Overvoltage protection threshold is as high as 6.8V±3%. Also, continuous current capability is as high as 3A.
Internally, the R5528Z001A consists of a reverse current protection circuit, a soft-start circuit, a startup debounce circuit, an undervoltage lockout (UVLO) circuit, and a thermal shutdown circuit.
The R5528Z001A is offered in a small and thin WLCSP-9-P1 package which achieves the smallest possible footprint solution on boards where area is limited.
