The VN540SP-E Power Switch ICs with Power Distribution HIGH SIDE SMART POWER manufactured by STMicroelectronics is a high side power control IC for DC/DC converter applications, with LED display, short circuit protection, over-voltage protection, and overtemperature protection. It is suitable for linear and switching regulators, load switches, and battery chargers. It integrates four independent channels with low on-resistance, and configurable control inputs that allow the user to choose between current or voltage regulation. Each channel is rated to handle up to 4A of continuous current and can be configured with an adjustable over-current/short-circuit or over-temperature protection. With its wide range of input voltage, the VN540SP-E is a cost-effective solution for mobile and industrial applications.
