General Description

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 dropping voltage between CSP pin and CSN pin.

Moreover, users can set over-/undervoltage threshold by the OVSET pin/UVSET pin to compare with the CSP voltage.
