65V, Low-Quiescent-Current, High-Voltage Linear Regulators with µP Reset and Watchdog TimerHigh-Voltage, Low-Quiescent-Current Linear Regulators Ideal for Automotive and Industrial Applications
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 withstand 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 regulator, the MAX5023/MAX5024 include an active-low HOLD input that allows for the implementation of a self-holding circuit without requiring external components. Setting active-low HOLD low after enabling the regulator, forces the regulator to remain on even if EN is subsequently set low. Releasing active-low 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 regulator"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-EP package.
