The LT4363CMS-1#PBF is an overvoltage protection regulator from Analog Devices that drives an external N-channel MOSFET. It operates across a wide supply voltage range of 4V to 80V and can withstand voltages down to -60V without damage. This device is suitable for automotive applications, including cold cranking conditions, due to its low 4V power supply requirement.
The LT4363 features an internal charge pump to turn on the N-channel MOSFET with minimal power loss. It includes an active current limit circuit that monitors voltage across an optional sense resistor, regulating the output to protect the MOSFET. The device also incorporates a fault timer that allows the load to continue functioning during short transient events.
Key electrical specifications include an internal reference voltage of 1.275V and current limit thresholds of 50mV (above 2V OUT) and 25mV (below 2V OUT). Resetting the part involves pulling the SHDN pin low for at least 100µs with a slew rate of at least 10V/ms.
This component is supplied in a CMS package, suitable for various power management applications requiring robust protection against voltage surges and overcurrent conditions.
The LT4363CMS-1#PBF operates from a supply voltage range of 4V to 80V.
The LT4363CMS-1#PBF provides overvoltage protection up to 80V.
The LT4363CMS-1#PBF can be pulled below ground potential by up to 60V without damage.
When the OUT pin potential is above 2V, the current limit is set to 50mV.
During a severe output short (OUT below 2V), the servo sense voltage is reduced to 25mV.
The internal reference voltage for the LT4363CMS-1#PBF is 1.275V.
To reset the part, pull the SHDN pin low for at least 100µs, then pull high with a slew rate of at least 10V/ms.
