Protected High Side Power Switch with Transient Suppression
Description
The HIP1090 is a Protected Power Interface Switch designed to suppress potentially damaging over-voltage transients with peak voltage source inputs ranging up to ±90V in amplitude. It is designed to be operated in a ‘hardwired’ pass-thru mode or as a high side power switch which controls the current flow through a PNP pass transistor of the IC. In either mode The HIP1090 has a low saturated forward voltage drop. The protected load circuit is connected to the output of the IC. As such, the HIP1090 operates as a transient suppressor where the PNP drive transistor is switched off when VIN is greater...
