MIC5014/5015
General Description
MIC5014 and MIC5015 MOSFET drivers are designed for
gate control of N-channel, enhancement-mode, power
MOSFETs used as high-side or low-side switches. The
MIC5014/5 can sustain an on-state output indefinitely.
The MIC5014/5 operates from a 2.75V to 30V supply. In high-
side configurations, the driver can control MOSFETs that
switch loads of up to 30V. In low-side configurations, with
separate supplies, the maximum switched voltage is limited
only by the MOSFET.
The MIC5014/5 has a TTL compatible control input. The
MIC5014 is noninverting while the MIC5015 is inverting.
The MIC5014/5 features an internal charge pump that can
sustain a gate voltage greater than the available supply
voltage. The driver is capable of turning on a logic-level
MOSFET from a 2.75V supply or a standard MOSFET from a
5V supply. The gate-to-source output voltage is internally
limited to approximately 15V.
The MIC5014/5 is protected against automotive load dump,
reversed battery, and inductive load spikes of –20V. The
driver’s overvoltage shutdown feature turns off the external
MOSFET at approximately 35V to protect the load against
power supply excursions.
The MIC5014 is an improved pin-for-pin compatible replace-
ment in many MIC5011 applications.
The MIC5014/5 is available in plastic 8-pin DIP and 8-pin
SOIC pacakges.
