The Olympus series of ICs are the industry’s smallest and robust integrated system protection solutions. The MAX17523/MAX17523A adjustable overvoltage and overcurrent protection device is ideal for protecting systems against positive and negative input voltage faults up to ±40V, and feature low 190mΩ (typ) RON integrated FETs. The adjustable overvoltage range in MAX17523 is between 6V and 36V, while the adjustable undervoltage range is between 4.5V and 24V. The adjustable overvoltage range in MAX17523A is between 6V and 36V, while the adjustable undervoltage range is between 4.2V 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 19V (typ). The MAX17523/MAX17523A also feature programmable current-limit protection up to 1A. The device can be set for autoretry, latch-off, or continuous fault response when an overcurrent event occurs. Once current reaches the threshold, the MAX17523/MAX17523A turn off after 21ms (typ) blanking time, and stay off during the retry period when set to autoretry mode. The devices latch off after the blanking time when set to latch-off mode. The devices limit the current continuously when set to continuous mode. The MAX17523/MAX17523A also feature reverse current and thermal shutdown protection. The MAX17523 and MAX17523A are available in a small, 16-pin (3mm x 3mm) TQFN package. The MAX17523 operates over the -40°C to +125°C extended temperature range.
