19-4325, Rev P; 10/94
Quad, High-Side MOSFE T 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 nor‘mverted outom that
swings from ground to the high-SIde voltage, The out-
puts dnve N-channel FETs in high-snde or low-side
switching aopl'cations, incluchrng a wide range of line-
and battery-powered applications
The MAX620/MAX621 are m;croprocessor compatible and
feature undervoltage lockout capability. Thes lockout
feature inmbits the FET driver outputs until the high-side
voltage reaches the proper level, as Indicated by a
Power-Ready ouipui.
The MAX620 requires three incxpcnsive charge-pump
capacitors The MAX621 has Internal capacitors -no
external comoonents are needed
