Low-Cost High- or Low-Side MOSFET Driver
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 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.
