IPS021S

IPS021S Description

The IPS021S is an integrated circuit (IC) power switch designed for general-purpose applications, featuring a low-side output configuration. Manufactured by Infineon Technologies, this obsolete component is housed in a D2PAK surface-mount package, ensuring robust mechanical stability and efficient heat dissipation. With a maximum output current of 1.8A and a load voltage rating up to 35V, the IPS021S is well-suited for managing power in various electronic systems. The device operates with a 1:1 input-to-output ratio, simplifying design integration. It includes essential fault protection mechanisms such as fixed current limiting and over-temperature protection, enhancing reliability and safety. The typical on-state resistance (Rds On) is 130mOhm, contributing to minimal power loss during operation. Despite its obsolescence, the IPS021S remains a viable option for legacy systems and specific applications where its unique features are advantageous.
