The ULQ2003ADG4 is a load driver and power distribution switch that is able to perform multiple tasks within a single integrated circuit. The ULQ2003ADG4 is great for applications where a system requires both high-side and low-side drive capabilities with high current output. It is suitable for a variety of high-power applications, such as LED backlighting, LCD panel power supply, DC-DC converter, motor drive, and power distribution switching.

The ULQ2003ADG4 operates from a 4 V to 18 V input voltage. This gives the device a wide variety of design parameters for applications where high voltage is needed. The output voltage range is adjustable from 4 V to 18 V, and the peak output current is 3 A. The ULQ2003ADG4 is also capable of regulating its own output voltage, allowing for automatic control to be implemented.

The ULQ2003ADG4’s power distribution switch allows for bidirectional induction current flow, as well as interface power supply capability, power detection, and load sharing. As such, the ULQ2003ADG4 is an essential operating element in power distribution systems.

When the ULQ2003ADG4 is used as a load driver, the output voltage is regulated and the output current can be regulated to maintain the constant voltage output or allow for quick dynamic response. The ULQ2003ADG4’s high-side driver can provide full-wave PWM or LVTTL control, while the low-side driver operates from either the H1 or the L1 terminal. The device also features two 2-phase, 2 MHz drive frequency configurations. The first configuration allows for constant current output, while the second allows for constant voltage output.

The ULQ2003ADG4’s low-side driver can be used to drive a variety of loads such as MOSFET, IGBT, bipolar transistors, and relays. The ULQ2003ADG4’s high-side driver can be used to drive power switches, IGBTs, and relays. The device also features an over-current protection feature to protect the load from excessive current.

The ULQ2003ADG4 is designed to be used in a wide variety of applications. This product is incredibly versatile, as it has multiple functions that can be implemented within a single integrated device. The device is perfect for applications where high power needs to be distributed and regulated, such as LED backlighting, LCD panel power supply, DC-DC converter, motor drive, and power distribution switching. It is an ideal choice for any application where two high-side and low-side drive capabilities are required.
