Power Distribution Switches, Load Drivers FAQ

How does the analog current sense function?

The device delivers a current proportional to the load current through the CURRENT SENSE pin when the CS_DIS pin is driven low or left open. If CS_DIS is driven high, the pin enters a high impedance condition.

What protections are included against electrical faults?

The device includes undervoltage shut-down, overvoltage clamp, load current limitation, protection against loss of ground and loss of VCC, and thermal shutdown with automatic restart.
