Analog Devices / Maxim Integrated MAX17561/2/3 Overvoltage & Overcurrent Protectors
Analog Devices MAX17561 and MAX17562 and MAX17563 Adjustable Overvoltage and Overcurrent Protectors offer robust industrial power protection with a wide +4.5V to +36V input supply range. The devices are ideal to protect systems against positive and negative input voltage faults up to Q40V and feature low 100mΩ (typ.) RON FETs.
The Analog Devices MAX17561/2/3 Protectors are housed in small 14-pin TSSOP packages and offer flexible design options to ease designs. The adjustable overvoltage protection range is between 6V and 36V, while the adjustable undervoltage protection range is between 4.5V and 24V. The overvoltage-lockout (OVLO) and undervoltage-lockout (UVLO) thresholds are set using optional external resistors. The factory-preset internal OVLO threshold is 33V (typ.) and the preset internal UVLO threshold is 19.2V (typ.).
