PMIC - LED Drivers are types of devices used to control LEDs. The BTS5672EAUMA2 is a switching power supply integrated circuit, categorized as a PMIC - LED Driver, and it is designed to drive high power LEDs with a constant current output.

The BTS5672EAUMA2 is a cost-efficient and reliable solution for high-power LEDs, effectively protecting the LED against any over-current, voltage and temperature. It also has an integrated dimming function and can also provide accuracy in current as low as 0.25mA.

The circuit includes a 1.7V to 25V voltage regulator, two external N-channel power MOSFETs, two built-in transistors, and a 74HC373PW latch to enable/disable the supply. The latch is controlled by external signals, as is the output current. The internal configuration of this PMIC-LED Driver provides up to 1.5 A of regulated output current and 2.5 A of peak output current.

The BTS5672EAUMA2 has a wide input range, from 4.5V to 37V, which allows the circuit to be connected to different sources with different voltages. It also includes an output enable/disable, dimming control, and enable/disable for the two external power MOSFETs. This allows the current to be adjusted as needed for an efficiency improvement. Additionally, an output shutoff feature can be activated for lower output current levels.

The BTS5672EAUMA2 can be used to power high intensity LEDs, from 0.5W to 25W range. It is designed with an automatic switching mode, which means the circuit will automatically detect when the LED needs to be turned off or turned on. This feature contributes to an energy savings, as it helps reduce the overall power consumption of the LED system.

The working principle of the BTS5672EAUMA2 is based on a buck switching mode. The IC can detect the input voltage range and adjust the current through an inverted feedback loop. When the input voltage decreases, the IC reduces output current to maintain the voltage across the LED constant. If the input voltage reaches a certain threshold, the IC will shut off the LED current supply.

In addition, the BTS5672EAUMA2 is designed to effectively dissipate the heat generated from the LED. This is done by using the thermal shut-down feature, which will turn off the circuit if the temperature exceeds a certain pre-set threshold. This feature helps to protect the LED from heat-damaged, as well as from excessive current.

BTS5672EAUMA2 is a cost-effective solution for driving high power LEDs. It can be used to drive any type of LED, from 0.5W to 25W. It has a wide input range, and its output can be adjusted with precision. Additionally, it has built-in protection features, to protect the LED from excessive currents and temperatures. This makes the BTS5672EAUMA2 an ideal choice for applications such as automotive lighting, street lighting, and other high-power LED applications.
