MIC5011
General Description
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 60μs typical with no
external components. Faster switching is achieved by add-
ing 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.
