MAX17613A/ MAX17613B/ MAX17613C
4.5V to 60V, 3A Current-Limiter with OV, UV and Reverse Protection
General Description
The Olympus series of ICs is the industry's smallest and most robust integrated system protection solution. The MAX17613A/MAX17613B/MAX17613C adjustable over
voltage and overcurrent protection devices are ideal to protect systems against positive and negative input
voltage faults up to +60V and -65V, and feature low 130mΩ (typ) RON FETs.
The adjustable input over
voltage protection range is 5.5V to 60V and the adjustable input under
voltage protection range is 4.5V to 59V. The input over
voltage-lockout (OVLO) and under
voltage-lockout (UVLO) thresholds are set using external resistors. Additionally, the devices offer an internal input under
voltage threshold at 4.2V (typ).
The devices feature programmable current-limit protection up to 3A; hence, controlling the inrush current at startup while charging high capacitance at the output. The currentlimit 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, continuous, or latchoff modes. The
voltage appearing on the SETI pin is proportional to the instantaneous current flowing through the device...
