The DMP2021UFDE-13 is a high-performance, MOSFET-based, single-channel, low-side switch designed for automotive applications. The switch provides for load switching, high-side current sensing, and current limiting. The DMP2021UFDE-13 is designed for low side load switching applications and for current monitoring applications.

The switch features an internal self-limiting feature that limits the switching current to 1A. The switch also features an adjustable current limit range of 0.25A to 4A with a 0.125A accuracy. The internal current limit is set using a single 0.020uF capacitor. The switch is built with a 0.35mm thick titanium gate oxide to provide superior thermal and electrical performance.

The MOSFET switch is powered by a 12V voltage source and provides superior protection against reverse battery conditions, overvoltage protection and overcurrent protection. The switch is designed to work with an external NPN transistor configured as an emitter-follower. The transistor provides low on-resistance (R DS(on) ) and a low gate capacitance. The external transistor provides a low on-resistance path for the DMP2021UFDE-13 switch and reduces power losses in the switching applications.

The DMP2021UFDE-13 switch has a wide operating temperature range of -40℃ to +105℃. The switch is rated for up to 4A current ratings and is protected against short circuit events. The switch also features low quiescent current and low voltage operation (1.4V).

The DMP2021UFDE-13 switch can be used in automotive applications such as load switching, current limit control, and current sensing applications. The switch is compatible with various microcontrollers such as the Atmel ATtiny, as well as with various FPGA and microprocessor technologies such as the Altera NIOS, and Microchip PIC Microcontrollers.

In short, the DMP2021UFDE-13 is a single-channel, low-side switch designed for automotive applications. The switch provides for load switching, high-side current sensing, and current limiting. The switch is suited for low side load switching applications and for current monitoring applications. The switch is built with a 0.35mm thick titanium gate oxide to provide superior thermal and electrical performance. The switch is powered by a 12V voltage source and is rated for up to 4A current ratings. The switch is compatible with various microcontrollers, FPGA and microprocessor technologies.
