The IPS5551T is a fully protected three terminal high
side switch with built-in short-circuit, over-temperature,
ESD protection, inductive load capability. The input
signal is referenced to Vcc. When the input voltage
Vcc - Vin is higher than the specified threshold, the
output power MOSFET is turned on. When the Vcc - Vin
is lower than the specified Vil threshold, the output
MOSFET is turned off. Input noise immunity is improved by an hysterisis. When the input is left floating,
an internal current source pulls it up to Vcc. The overcurrent protection latches off the high side switch if the
output current exceeds the specified Isd. The overtemperature protection latches off the switch if the
junction temperature exceeds the specified value Tsd.
The device is reset by opening the input pin high.
