General Description
The MAX5023/MAX5024 high-voltage linear regulators
operate from a +6.5V to +65V input voltage and deliver
up to 150mA of output current. These devices consume
only 60μA of quiescent current with no load and with-
stand a -60V reverse-battery voltage at the input. The
MAX5023/MAX5024 include an active-low internal
microprocessor (μP) reset circuit that asserts when the
regulator output drops below the preset output voltage
threshold by 7.5% or 12.5%, depending on the device
selected. Both devices are available with a fixed +3.3V
or +5V output. These devices are short-
circuit protected and include thermal shutdown.
In addition to an enable input to turn on or off the regu-
lator, the MAX5023/MAX5024 include a
HOLD
input
that allows for the implementation of a self-holding
circuit without requiring external components. Setting
HOLD
low after enabling the regulator, forces the regu-
lator to remain on even if EN is subsequently set low.
Releasing
HOLD
shuts down the regulator.
The MAX5023 includes a watchdog input that monitors a
pulse train from the μP and generates reset pulses if the
watchdog input remains high or low for a duration longer
than the 1.6s watchdog timeout period. The MAX5024
includes a SET input which, when connected to ground,
selects a preset output voltage of +3.3V (MAX5024S/
MAX5024T) or +5V (MAX5024L/MAX5024M). Set the
adjustable output voltage by connecting SET to the regu-
lator’s output through a resistive-divider network.
The MAX5023/MAX5024 operate over the automotive
temperature range (-40°C to +125°C) and are available in
a thermally enhanced, surface-mount 8-pin SO package.
