The MP6219DN-LF is a power management integrated circuit (PMIC) part of the Power Distribution Switches, Load Drivers category.

The MP6219DN-LF is a power distribution switch-load driver (DS-LD) IC that operates from an input voltage source supplying up to 7V. It supports a wide range of voltage levels from 100mV to 7V across the input and output pins. This device suits a wide range of consumer electronic applications such as desktop and laptop computers and portable electronic devices.

The MP6219DN-LF features a low quiescent current of only 10µA, making it highly efficient. Its robust design allows for a maximum combined series voltage of 8.5V across the two switches, enabling high power delivery capability. The integrated high side switch can drive a load up to 2A, while the low side switch can handle up to 8A. This device can be paralleled with other higher current rated parts, allowing a higher current to be sourced from the system while conserving board space by using fewer components. The device also supports 1µA shutdown mode. It is available in an 8-pin ePad-TO263 package.

The MP6219DN-LF works by pulling the gate of the high side MOSFET high and connecting it to the VIN pin, and pulling the low side MOSFET gate low and connecting it to the VIN pin. This allows current to flow from VIN through the high side MOSFET, out of VOUT and into the low side MOSFET. This process can be reversed if the high or low side switches are enabled, allowing power to be switched from the VIN or VOUT pins.

The device supports a variety of output frequencies, from 50KHz to 500KHz, allowing for operation in low noise environments. The integrated dual-channel driver allows for separate control of the high and low side switches, allowing for better power delivery and load balancing. The device also has a built-in temperature protection feature that prevents the device from overheating. The device also supports a feature that allows the user to enable or disable the low side MOSFET.

The MP6219DN-LF is an ideal solution for applications that require efficient, cost-effective and easy to use switching between a power source and the output load. Its low quiescent current consumption and integrated temperature protection make it an ideal choice for a wide range of consumer electronic applications.
