MIC5060
Ultra Small High-Side MOSFET Driver
General Description
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.
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.
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.
The MIC5060 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.
The MIC5060 is available in 3mm x 3mm MLF^® package.
