The MAX14588ETE+T from Analog Devices is an adjustable overvoltage and overcurrent protection device designed to protect sensitive circuits from positive and negative input voltage faults up to ±40V. It integrates a low on-resistance (190mΩ typical) N-channel MOSFET to minimize power dissipation and voltage drop.
The device offers programmable overvoltage lockout (OVLO) thresholds from 6V to 36V and undervoltage lockout (UVLO) thresholds from 4.5V to 24V, set via external resistors. Factory preset OVLO and UVLO thresholds are 33V and 19V typical, respectively. The current limit is programmable from 0.15A to 1A, with selectable fault response modes: autoretry, latch-off, or continuous current limiting. An overcurrent blanking time of 21ms helps prevent nuisance tripping.
The MAX14588 operates over the -40°C to +125°C temperature range and is housed in a compact 16-pin TQFN (3mm x 3mm) package with an exposed pad for efficient thermal management. It includes reverse current flow control and thermal shutdown protection, making it suitable for industrial sensor systems, factory automation, and process instrumentation applications.
