TDE3247FP Application Field and Working Principle

TDE3247FP is a PMIC (Power Management Integrated Circuit) load driver solution by STMicroelectronics. PMIC is an integrated circuit designed to provide efficient solutions to efficiently manage the power needs of electronic and battery operated devices, and is designed to be a "one-stop shop" for all power control needs. The TDE3247FP is part of ST’s Power Distribution Switches, Load Drivers portfolio, and is designed for switching and driving applications.

The TDE3247FP offers a three-channel, low-side enhanced power switch for enhancing robustness across a wide range of automotive, industrial and domestic device applications. The device offers a highly scalable, low gate-charge shutdown, and ultra-low RDS(on) for low power dissipation and greatly improved efficiency in switching applications. The TDE3247FP has a 1.25 V dropout voltage, making it ideal for low-voltage applications. In addition, the device offers an active low enabling input, open-drain outputs, and thermal shutdown protection.

In addition to offering excellent robustness, the TDE3247FP provides efficient and flexible power management solutions. It features a synchronous, self-timing multi-channel switching and driving architecture, as well as a wide supply range of 10 V to 55 V. The wide input voltage range enables the device to be used in a variety of automotive, industrial and domestic application settings, while the integrated fault protection features provide enhanced system protection.

The working principle behind the TDE3247FP is relatively straightforward. The device works by using a multi-level active-low enable input to control the operation of the device. When enabled, the device will produce three independent outputs which provide power to the respective loads. The integrated output stages are synchronous, meaning that each channel can switch up to 100 A at a peak current of 200 A. This provides excellent application flexibility, making the device well-suited for a wide range of automotive, industrial and domestic device applications.
