MAX14562 Datasheet, PDF (9/10 Pages) Maxim Integrated Products – 36V-Capable Overvoltage Protector with Regulated Output Voltage

36V-Capable Overvoltage Protector with
Regulated Output Voltage
Overvoltage Lockout Mode (OVLO)
When IN goes above the overvoltage lockout threshold
(VOVLO), OUT is disconnected from IN and ACOK is
deasserted. Power dissipation increases when the input
goes higher than VPROV. The overvoltage lockout thresh-
old is set to further the power dissipation. When IN drops
below VOVLO, the debounce time starts counting. After
the debounce time (2 x tDEB), OUT follows IN again and
ACOK is asserted.
Thermal Shutdown
The MAX14562 features a thermal shutdown function
necessary to protect the device. The device turns off
and ACOK is deasserted when the junction temperature
exceeds +150NC (typ). When the temperature drops
20NC (typ) below 150NC (typ), the device turns back on
and Q1 is turned on after the debounce time.
Applications Information
Power-Supply Decoupling
Bypass IN pin(s) to ground with a 1FF or larger ceramic
capacitor placed as close as possible to the device.
PROCESS: BiCMOS
