RT9553A - High Accuracy Current/Voltage Sensing/Protection

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.

Features

  • Common Mode Input Range up to 24V.
  • VCC Operating Current : 200μA.
  • VCC Shutdown Current : 10μA (under S3/S4/S5).
  • Programmable Over-Current Level.
  • One Shot.

® RT9553A High Accuracy Current/Voltage Sensing and Protection IC 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. The RT9553A is a available in the WDFN-10L 3x3 package. Ordering Information RT9553A Package Type QW : WDFN-10L 3x3 (W-Type) Lead Plating System G : Green (Halogen Free and Pb Free) Note : Richtek products are :  RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020.  Suitable for use in SnPb or Pb-free soldering processes.
