The TC4423CPA is an integrated circuit (IC) manufactured by Microchip. It is a driver module with 3A low-side output and two channels. This device has 8-pin PDIP tube for easy installation. It is capable of driving a relatively large current load to drive the external device. The TC4423CPA is designed to provide protection for the external device against excessive or reverse current or voltage. It is suitable for low voltage applications, such as battery-powered products, because of its low power consumption. The TC4423CPA is capable of operating at supply voltage up to 36V and can be used for both switching applications or microcontroller I/O loads. The IC features an adjustable input under-voltage protection, and it is has short-circuit failure protection.
