MIC94068YML-TR

Power Distribution Switches and Load Drivers

The MIC94068YML-TR is a family of compact three-channel, low-dropout (LDO) power distribution switches and load drivers. It is optimized for space-constrained applications and offers a high level of integration, low power consumption, and robust performance. The MIC94068YML-TR is a highly efficient, time-saving alternative to discrete designs with low current transistors and other components.

This cost-effective device is capable of driving up to 24V of distributed supply. Its robust design enables it to provide many years of long-term operating reliability under diverse environmental conditions and at low operating power levels. In addition, it is compatible with a range of microcontrollers and other digital devices, making it an ideal choice for battery powered applications.

Application Field and Working Principle

The MIC94068YML-TR is based on a two-stage architecture, which consists of two distinct power transistors. The first stage is a high-voltage (HV) switch, which is responsible for controlling the main supply voltage. The second stage is a low-voltage (LV) switch, which is responsible for controlling the output voltage. Both the HV and LV switches are controlled by the same voltage level, thus eliminating the need for any further level shifting.

At the core of the MIC94068YML-TR is a charge-pump LDO (Low Dropout Regulator) controller. The combination of the LDO controller with the two transistors enables the device to quickly and efficiently step down the supply voltage level to its desired output voltage. The device is capable of handling a wide range of input-voltage levels, from 3.2V up to 24V, making it suitable for a wide range of applications.

The MIC94068YML-TR also features an on-chip programmable timer for Load Enable/Disable control. It also features adjustable output current limiting and provides a continuous current limit of 5A. The output voltage can also be programmed using hysteresis to enhance the system robustness and reliability.

The MIC94068YML-TR is also equipped with an over-voltage protection circuitry to protect the device from hazardous high-voltage transients. Additionally, the device is also provided with a soft-start circuitry to subsequently avoid inrush currents to the system when power is applied, along with a Thermal Shutdown Protection (TSP) monitor, which automatically de-activates the output when the die temperature exceeds a pre-determined threshold.

The MIC94068YML-TR is an efficient and compact solution for various power distribution and load-driving needs. It provides a robust solution for battery-powered and other applications requiring high-efficiency, low leakage current, and low power dissipation.
