Description
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 im-
proved by an hysterisis. When the input is left floating,
an internal current source pulls it up to Vcc. The over-
current protection latches off the high side switch if the
output current exceeds the specified Isd. The over-
temperature protection latches off the switch if the
junction temperature exceeds the specified value Tsd.
The device is reset by opening the input pin high.
