Overview

MIC5012 Micrel MIC5012 Dual High- or Low-Side MOSFET Driver Not Recommended for New Designs General Description The MIC5012 is the dual 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 highside power switch applications.
The 14-pin MIC5012 is extremely easy to use, requiring only a power FET and nominal supply decoupling to implement either a high- or low-side switch.
The MIC5012 charges a 1nF load in 60µs typical.
Operation down to 4.
75V allows the MIC5012 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 MIC5012 for ultrahigh current applications.
Other members of the Micrel driver family include the MIC5010 full-featured driver, MIC5011 minimum parts count driver, and MIC5013 protected 8-pin driver.
Features • 4.
75V to 32V operation • 2 independent drivers; implements high and low side drivers • Less than 1µA standby current in the “off” state per channel • Available in small outline SOIC packages • Internal charge pump to drive the gate of an N-channel power FET above supply • Internal zener clamp for gate protection • Minimum external parts count • Can be used to boost drive to low-side power FETs operating on logic supplies • Independent supply pins for half-bridge applications Applications • • • • • Lamp drivers Motion Control Heater switching Power bus switching Half or full H-bridge drivers For new designs, Micrel recommends the pin-compatible MIC5016 dual MOSFET driver.
