MIC5014/5015

Low-Cost High- or Low-Side MOSFET Driver

Final Information

Features

General Description

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. The • 15µA typical off-state current

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

• Operates in high-side or low-side configurations

• 1µA control input pull-off

• Inverting and noninverting versions

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.

Applications

• Automotive electrical load control

• Battery-powered computer power management

• Lamp control

• Heater control

• Motor 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 external

MOSFET at approximately 35V to protect the load against

power supply excursions.

• Power bus switching

The MIC5014 is an improved pin-for-pin compatible replace-

ment in many MIC5011 applications.

Ordering Information

The MIC5014/5 is available in plastic 8-pin DIP and 8-pin

SOIC pacakges.
