MAX17608, MAX17609, and MAX17610 Reverse-Voltage Protectors

Maxim Integrated's 4.5 V to 60 V, 1 A, OV, UV, reverse-voltage protectors with forward and reverse current limit

Image of Maxim's MAX17608, MAX17609, and MAX17610 Reverse-Voltage ProtectorsMaxim's MAX176xx adjustable overvoltage and overcurrent protection devices are ideal for protecting systems against positive and negative input voltage faults up to +60 V and -65 V and feature low 260 mΩ (typical) RON FETs. With adjustable input overvoltage protection range of 5.5 V to 60 V and the adjustable input undervoltage protection range of 4.5 V to 59 V, 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 4 V (typical).

These devices offer programmable current-limit protection up to 1 A; hence, controlling the inrush current at startup while charging high capacitances at the output. The 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 the current-limit condition: auto retry, continuous, 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.
