MIC5011 Micrel, Inc. MIC5011
Minimum Parts High-or Low-Side MOSFET Driver General Description Features The MIC5011 is the “minimum parts count” member of the
Micrel MIC501X driver family. These ICs are designed to
drive the gate of an N-channel power MOSFET above the
supply rail in high-side power switch applications. The 8-pin
MIC5011 is extremely easy to use, requiring only a power
FET and nominal supply decoupling to implement either a
high-or low-side switch.
The MIC5011 charges a 1nF load in 60Вµs typical with no
external components. Faster switching is achieved by adding two 1nF charge pump capacitors. Operation down to
4.75V allows the MIC5011 to drive standard MOSFETs in
5V low-side applications by boosting the gate voltage above
the logic supply. In addition, multiple paralleled MOSFETs
can be driven by a single MIC5011 for ultra-high current
applications.
Other members of the Micrel driver family include the
MIC5013 protected 8-pin driver.
For new designs, Micrel recommends the pin-compatible
MIC5014 MOSFET driver. 4.75V to 32V operation Less than 1µA standby current in the “off” state Internal charge pump to drive the gate of an N-channel
