FULLY PROTECTED POWER MOSFET SWITCH
Data Sheet No.PD 60148-K
Description
The IPS021/IPS021S are fully protected three terminal
SMART POWER MOSFETs that feature over-current,
over-temperature, ESD protection and drain to source
active clamp.These devices combine a HEXFET
POWER MOSFET and a gate driver. They offer full
protection and high reliability required in harsh envi-
ronments. The driver allows short switching times
and provides efficient protection by turning OFF the
power MOSFET when the temperature exceeds 165
o
C
or when the drain current reaches 5A. These devices
restart once the input is cycled. The avalanche capa-
bility is significantly enhanced by the active clamp
and covers most inductive load demagnetizations.

(2) Operations at higher switching frequencies is possible. See Appl. Notes.
Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters
are referenced to SOURCE lead. (TAmbient = 25
o
C unless otherwise specified). PCB mounting uses the standard foot-
print with 70
m copper thickness.
