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 high- side 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, paral- leled MOSFETs can be driven by a single MIC5012 for ultra- high 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. For new designs, Micrel recommends the pin-compatible MIC5016 dual MOSFET driver.
The MIC5012 is part of Micrel's MIC501X driver family and provides two independent drivers for high‑side or low‑side MOSFET switching. It operates from 4.75 V to 32 V, includes an internal charge‑pump to boost gate voltage, and features a zener clamp for gate protection.
The device is supplied in 14‑pin DIP and 16‑pin wide‑SOIC packages, draws less than 1 A standby current per channel, and is rated for temperatures from –40 °C to +85 °C. It is not recommended for new designs, with the MIC5016 suggested as a pin‑compatible replacement.
