The NCV4294CSN50T1G is an integrated circuit (IC) component designed for power management applications. This IC is part of the NCV429x family of devices manufactured by ON Semiconductor. It is specifically designed for automotive applications, where it provides high-performance solutions for a wide range of power supply and monitoring functions.
The NCV4294CSN50T1G offers several key features that make it suitable for automotive power management applications. Firstly, it operates over a wide input voltage range of 3.5V to 36V, allowing it to handle various battery voltages commonly found in automotive systems. This wide input voltage range enables its usage in cars, trucks, and other vehicles.
One of the notable features of this IC is its capability to handle load dumps and double battery jump-start scenarios. Load dumps occur when the battery is disconnected with the alternator running, causing a sudden voltage spike. The NCV4294CSN50T1G can withstand load dumps up to 40V and protects the downstream circuitry from voltage overshoots.
For power supply monitoring, this IC offers a programmable undervoltage lockout (UVLO) feature. This UVLO function protects sensitive electronics by monitoring the input voltage and ensuring it remains above a user-defined threshold. In case the input voltage drops below this threshold, the NCV4294CSN50T1G can trigger an alarm or shut down the system to prevent any potential damage
