CS3706
Dual Output Driver
Description
The CS3706 integrated circuit pro-
vides an interface between low-
level TTL inputs and high-power
switching devices such as power
MOSFETs. A typical application is
single-ended PWM control to push-
pull power control conversion.
The primary function of this device
is to convert a bipolar single-ended
low current digital input to a pair of
totem pole outputs which can
source or sink up to 1.5A. An inter-
nal flip-flop, driven by double-
pulse suppression logic, can be
enabled to provide single-ended to
push-pull conversion. With the flip-
flop disabled, the outputs work in
parallel for 3.0A capability.
Protection functions are also includ-
ed for pulse-by-pulse current limit-
ing, automatic deadband control
and thermal shutdown.
