Quad, High-Side MOSFET Drivers
General Description
The MAX620/MAX621 incorporate four MOSFET drivers
and a charge-pump high-side power supply to power
high-side switching and control circuits, The charge
pumo delivers a regulated output voltage 11V greater
than Vcc to the drivers, which then translate a
TTL/CMOS ,nput signal to a hor‘inverted cutout that
swings from ground to the nigh-side vo'tage. The out-
puts dnve N-channel FETs in high-side or Tow-side
switching aoplications, including a wide range of line-
and battery-powered applications.
The MAX620/MAX621 are microprocessor compatible and
feature undervoltage lockout capability. This lockout
feature inhibits the FET driver outputs until the high-side
voltage reaches the proper level, as indicated by a
Power-Ready output.
The MAX62O requires three incxpcnsive charge-pump
capacitors, The MAX621 has internal capacitors -no
external comoonents are needed
Applications
