LTC4211

First generation single supply Hot Swap controllers, such as the LTC1422, combine the features of various discrete inrush limiting circuits into a single IC, including an electronic circuit breaker, adjustable power-up rate, reset output, high-side MOSFET gate drive, undervoltage lockout and a wide operating voltage range. The LTC4211 advances these features by adding a dual level, dual response time electronic circuit breaker, adjustable soft-start with inrush current limiting, fault detection, faster ...
