LTC436x Series Overvoltage Overcurrent Protection Controllers

Linear Technology's LTC436x family features fast shutdown to protect low voltage electronics

LTC436x Series Overvoltage / Overcurrent Protection ControllersLinear Technology's LTC436x overvoltage protection family brings a number of advantages to low voltage, portable applications. All devices feature 2% accurate 5.8V overvoltage protection with fast shutdown of 1 μs to protect low voltage electronics from damage. High input overvoltage protection of 80 V with the LTC4360 and LTC4361 and 28 V with the LTC4362 provides protection from high voltage transients without requiring transient voltage suppressors or input capacitors in most applications. All devices feature a shutdown mode that gently puts the device into a low power mode, regardless of the input voltage, providing a low power dissipation mode for power-critical portable applications.
