MIC4223/MIC4224/MIC4225
Dual 4A, 4.5V to 18V, 15ns Switch Time,
Low-Side MOSFET Drivers with Enable
General Description
The MIC4223/MIC4224/MIC4225 are a family of a dual 4A,
High-Speed, Low-side MOSFET drivers with logic-level
driver enables. The devices are fabricated on Micrel’s
Bipolar/CMOS/DMOS (BCD) process and operate from a
4.5V to 18V supply voltage. The devices parallel Bipolar
and CMOS output stage architecture provides high-current
throughout the MOSFETs Miller Region allowing the driver
to sink and source 4A of peak current from a 12V supply
and quickly charge and discharge a 2000pF load
capacitance in under 15ns, while allowing the outputs to
swing within 0.3V of V DD and 0.16V of ground.
The MIC4223/MIC4224/MIC4225 driver and enable inputs
feature TTL and CMOS logic-level thresholds which are
independent of supply voltage. Each driver features a
dedicated active-high enable input which is internally
pulled high to V DD through 100k ? , allowing the pins to be
left unconnected if it is not required to disable the driver
outputs. The driver inputs have been designed to protect
against ground bounce and are protected to withstand -5V
of voltage swing at -40mA. Driver outputs are also
protected to withstand 500mA of reverse current.
The MIC4223/MIC4224/MIC4225 are available in three
configurations using industry standard pin out; dual
inverting (MIC4223), dual non-inverting (MIC4224) and
complimentary (MIC4225). They are available in 8-pin
SOIC and thermally enhanced e-PAD 8-pin MSOP and
support operating junction temperatures from -40°C to
+125°C.
