SGM48523C/SGM48524C
Dual 5A, High-Speed, Low-Side Gate Drivers
with Negative Input Voltage Capability
GENERAL DESCRIPTION
FEATURES
The SGM48523C and SGM48524C are dual high-
speed low-side gate drivers for power switches. They
have rail-to-rail driving capability and can sink or source
up to 5A peak current with capacitive loads. The
propagation delays are very short and well matched
between the two channels that make the device well
suited for applications that need accurate dual gate
driving such as synchronous rectifiers. The matched
propagation delays also allow for paralleling the two
channels when higher driving current is required for
example for paralleled switches. The input voltage
thresholds are fixed, independent of supply voltage
(VDD), and compatible with low voltage TTL and CMOS
logic. Noise immunity is excellent due to the wide
hysteresis window between the input low and high
thresholds. The devices have internal pull-up/pull-down
resistors on the input pins to ensure low state on the
driver output when the input is floating.
