MIC5060
Ultra Small High-Side MOSFET Driver
General Description
Features
The MIC5060 MOSFET driver is designed for gate control
of N-Channel, enhancement-mode, and power MOSFETs
used as high-side or low-side switches. The MIC5060 can
sustain an on-state output indefinitely.
• 2.75V to 30V operation
• 100µA maximum supply current (5V supply)
• 15µA typical off-state current
• Internal charge pump
The MIC5060 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.
• TTL-compatible input
• Withstands 60V transient (load dump)
• Reverse battery protected to –20V
• Inductive spike protected to –20V
• Overvoltage shutdown at 35V
• Internal 15V gate protection
The MIC5060 has a non-inverting, TTL-compatible control
input.
The MIC5060 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.
• Minimum external parts
• Operates in high-side or low-side configurations
• 1µA control input pull-off
• Available in 8-pin 3mm x 3mm MLF® package
Applications
The MIC5060 is protected against automotive load dump,
reversed battery, and inductive load spikes of –20V.
• Notebook Battery safety switches
• UMPC and Web Tablet Battery protection
• Battery-powered computer power management
• General MOSFET switch applications
• Power bus switching
The driver’s overvoltage shutdown feature turns off the
external MOSFET at approximately 35V to protect the load
against power supply excursions.
The MIC5060 is available in 3mm x 3mm MLF® package.
