General Description
The MIC5022 half-bridge MOSFET driver is designed to
operate at frequencies up to 100kHz (5kHz PWM for 2% to
100% duty cycle) and is an ideal choice for high speed
applications such as motor control and SMPS (switch mode
power supplies).
A rising or falling edge on the input results in a current source
pulse or sink pulse on the gate outputs. This output current
pulse can turn on a 2000pF MOSFET in approximately 1
μ
s.
The MIC5022 then supplies a limited current (< 2mA), if
necessary, to maintain the output states.
Two overcurrent comparators with nominal trip voltages of
50mV make the MIC5022 ideal for use with current sensing
MOSFETs. External low value resistors may be used instead
of sensing MOSFETs for more precise overcurrent control.
Optional external capacitors placed on the C
TH
and C
TL
pins
may be used to individually control the current shutdown duty
cycles from approximately 20% to <1%. Duty cycles from
20% to about 75% are possible with individual pull-up resis-
tors from C
TL
and C
TH
to V
DD
. An open collector output
provides a fault indication when either sense input is tripped.
The MIC5022 is available in 16-pin wide SOIC and 14-pin
plastic DIP packages.
Other members of the MIC502x family include the MIC5020
low-side driver and the MIC5021 high-side driver.
