MIC5014/5015

Low-Cost High- or Low-Side MOSFET Driver

General Description

Features

MIC5014 and MIC5015 MOSFET drivers are designed for • 2.75V to 30V operation

gate control of N-channel, enhancement-mode, power • 100µA maximum supply current (5V supply)

MOSFETs used as high-side or low-side switches. • 15µA typical off-state current

The MIC5014/5 can sustain an on-state output indefinitely.

• Internal charge pump

• TTL compatible input

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.

• Withstands 60V transient (load dump)

• Reverse battery protected to –20V

• Inductive spike protected to –20V

• Overvoltage shutdown at 35V

• Internal 15V gate protection

• Minimum external parts

The MIC5014/5 has a TTL compatible control input.

The MIC5014 is noninverting while the MIC5015 is inverting.

• Operates in high-side or low-side configurations

• 1µA control input pull-off

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.

• Inverting and noninverting versions

Applications

• Automotive electrical load control

• Battery-powered computer power management

• Lamp control

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 exter-

nal MOSFET at approximately 35V to protect the load against

power supply excursions.

• Heater control

• Motor control

• Power bus switching

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.
