RT9553A Overview
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 pare that senses dropping voltage between CSP pin and CSN pin. Moreover, users can set over-/undervoltage threshold by the OVSET pin/UVSET pin to pare with the CSP voltage.
