The Olympus series of ICs are the industry’s smallest and robust integrated system protection solutions. The MAX17608/MAX17609/MAX17610 adjustable overvoltage and overcurrent protection devices are ideal to protect systems against positive and negative input voltage faults up to +60V and -65V, and feature low 260mΩ (typ) RON FETs.

The adjustable input overvoltage protection range is 5.5V to 60V and the adjustable input undervoltage protection range is 4.5V to 59V. The input overvoltage-lockout (OVLO) and undervoltage-lockout (UVLO) thresholds are set using external resistors. Additionally, the devices offer an internal input undervoltage threshold at 4V (typ).

The devices feature programmable current-limit protection up to 1A; hence, controlling the inrush current at startup while charging high capacitances at the output. Current-limit threshold is programmed by connecting a resistor from the SETI pin to GND. When the device current reaches the programmed threshold, the device prevents further increases in current by modulating the FET resistance. The devices can be programmed to behave in three different ways under current-limit condition: Autoretry, Continous, or Latch-off modes. The voltage appearing on the SETI pin is proportional to the instantaneous current flowing through the device and is read by an ADC.

MAX17608 and MAX17610 block current flowing in the reverse direction (i.e., from OUT to IN) whereas MAX17609 allows current flow in the reverse direction. The devices feature thermal shutdown protection against excessive power dissipation.

The devices are available in a small, 12-pin (3mm x 3mm) TDFN-EP package. The devices operate over the -40°C to +125°C extended temperature range.
