Мониторы и регуляторы тока и мощности MAX17523ETE+

Устройство защиты от перенапряжения и перегрузки по току , 4.5В до 36В вход, TQFN-16

The MAX17523ETE+ is a 1A adjustable overcurrent and overvoltage protector with high accuracy in 16 pin TQFN package. This device is ideal for protecting systems against positive and negative input voltage faults up to ±40V and feature low 190mohm (typ) RON integrated FETs. The adjustable overvoltage range is between 6V and 36V, while the adjustable undervoltage range is between 4.5V 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). It also features 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. It is used in sensor systems, condition monitoring, factory sensors, process analytics and weighing and batching systems.
