MIC5060 Ultra Small High-Side MOSFET Driver General Description Features The MIC5060 MOSFET driver is designed for gate control 2.75V to 30V operation of N-Channel, enhancement-mode, and power MOSFETs 100A maximum supply current (5V supply) used as high-side or low-side switches. The MIC5060 can 15A typical off-state current sustain an on-state output indefinitely. Internal charge pump The MIC5060 operates from a 2.75V to 30V supply. In TTL-compatible input high-side configurations, the driver can control MOSFETs that switch loads of up to 30V. In low-side configurations, Withstands 60V transient (load dump) with separate supplies, the maximum switched voltage is Reverse battery protected to 20V limited only by the MOSFET. Inductive spike protected to 20V The MIC5060 has a non-inverting, TTL-compatible control Overvoltage shutdown at 35V input. Internal 15V gate protection The MIC5060 features an internal charge pump that can Minimum external parts sustain a gate voltage greater than the available supply Operates in high-side or low-side configurations voltage. The driver is capable of turning on a logic-level MOSFET from a 2.75V supply or a standard MOSFET 1A control input pull-off from a 5V supply. The gate-to-source output voltage is Available in 8-pin 3mm x 3mm MLF package internally limited to approximately 15V. The MIC5060 is protected against automotive load dump, Applications reversed battery, and inductive load spikes of 20V. Notebook Battery safety switches The drivers overvoltage shutdown feature turns off the UMPC and Web Tablet Battery protection external MOSFET at approximately 35V to protect the load Battery-powered computer power management against power supply excursions. General MOSFET switch applications The MIC5060 is available in 3mm x 3mm MLF package. Power bus switching Datasheets and support documentation can be found on Micrels web site at: www.micrel.com.

Must be decoupled to isolate from large transients caused by the power MOSFET drain. 10F is recommended close to pins 1 and 4. 2 Input Turns on power MOSFET when taken above (or below) threshold (1.0V typical). Pin 2 requires ~ 1A to switch. 3 Source Connects to source lead of power MOSFET and is the return for the gate clamp zener. Pin 3 can safely swing to 20V when turning off inductive loads. 4 Ground Ground. 5 Gate Drives and clamps the gate of the power MOSFET. 6, 7, 8 NC Not internally connected.
