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 improved 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.
