General Description
MIC5016 and MIC5017 dual MOSFET drivers are designed for gate control of N-channel, enhancement-mode, power MOSFETs used as high-side or low-side switches. The MIC5016/7 can sustain an on-state output indefinitely.
The MIC5016/7 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.
FEATUREs
• 2.75V to 30V operation
• 100µA maximum supply current (5V supply)

• 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
