MIC5014/5015 Micrel, Inc. MIC5014/5015
Low-Cost High-or Low-Side MOSFET Driver General Description Features 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 highside 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. 2.75V to 30V operation
