The RT9553A is designed for over-current detection and over-/under-voltage protection.
It provides users to set over-current threshold by the ILIM pin to compare that senses droping voltage between CSP pin and CSN pin. Moreover, users can set over-/under-voltage threshold by the OVSET pin/UVSET pin to compare with the CSP voltage. The RT9553A is a available in the WDFN-10L 3x3 package.
