FUNCTIONAL DESCRIPTION
The Triple High-Side Power-MOS Driver features
all necessary control and protection functions to
switch on three Power-MOS transistors operating
as High-Side switches in automotive electronic
control units. The key application field is relays re-
placement in systems where high current loads,
usually motors with nominal currents of about 40A
connected to ground, has to be switched.
A high signal at the EN pin enables all three
channels. With enable low gates are clamped to
ground. In this condition the gate sink current is
higher than the specified 3mA. An enable low sig-
nal makes also a reset of the timer.
A low signal at the inputs switch on the gates of
the external MOS. A short circuit at the input
leads to permanent activation of the concerned
channel. In this case the device can be disabled
with the enable pin. The charge pump loading is
not influenced due to the enable input.
An external N-channel MOS driver in high side
configuration needs a gate driving voltage higher
than V
S
. It is generated by means of a charge
pump with integrated charge transfer capacitors
and one external charge storage capacitor C
CP
.
The charge pump is dimensioned to load a ca-

NOTE: Not measured guaranteed by design
Function is given for supply voltage down to 5.5V. Function means: The channels are controlled from the
inputs, some other parameters may exceed the limit. In this case the programming voltage and timer
threshold will be lower. This leads to a lower protection threshold and time.
