The MAX17561/MAX17562/MAX17563 adjustable overvoltage and overcurrent-protection devices are ideal to protect systems against positive and negative input voltage faults up to ±40V and feature low 100mΩ (typ) RON FETs.
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).
The ICs also feature programmable current-limit protection up to 4.2A. Once current reaches the threshold, the MAX17561 turns off after the 20.7ms (typ) blanking time and stays off during the retry period. The MAX17562 latches off after the blanking time, and the MAX17563 limits the current continuously. In addition, these devices feature reverse current and thermal-shutdown protection. The ICs are available in a small 14-pin TSSOP (5mm x 6.5mm) package and are specified over the extended -40°C to +125°C temperature range.
