These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

When the output load exceeds the current-limit threshold or a short is present, the TPS209x limits the output

current to a safe level by switching into a constant-current mode, pulling the overcurrent (OCx) logic output low.

When continuous heavy overloads and short circuits increase the power dissipation in the switch causing the

junction temperature to rise, a thermal protection circuit shuts off the switch to prevent damage. Recovery from a

thermal shutdown is automatic once the device has cooled sufficiently. Internal circuitry ensures the switch

remains off until valid input voltage is present. The TPS209x devices are designed to current limit at 0.5-A load.
