Working Principle

The ULQ2004ADG4 PMIC works by controlling the distribution of loads. It uses its integrated protection feature to prevent current, voltage, and temperature overloads. The ULQ2004ADG4 is composed of four independent load channels, each with their own current and voltage monitoring capabilities. Each channel can power up or down with a switching frequency up to 1MHz and can deliver up to 20 A.

The ULQ2004ADG4 also features integrated power and thermal monitoring functions. When a preset condition is exceeded, it halts the load distribution and shuts down the system as a preventive measure. The ULQ2004ADG4 also offers an adjustable wake-up time, adjustable pulse width modulation (PWM), and enables standby and low power modes.

Conclusion

The ULQ2004ADG4 PMIC is a powerful load distribution switch and load driver that provides a wide range of current and voltage management capabilities for a variety of consumer and commercial applications. Its integrated protection feature provides a reliable and efficient way to protect against overcurrent, overvoltage, and overtemperature conditions. The ULQ2004ADG4 also includes an adjustable wake-up time, adjustable PWM, and low power modes, thus making it an ideal choice for low power applications.
