UDN2987A-6-T, belonging to the PMIC (Power Management Integrated Circuit) family, is a high-performance power distribution switch, load driver, and current-limiting circuit in one. It has excellent high-frequency performance, high peak-pulse current capability, and improved thermal and electrical interface. The device is designed to control multiple DC motors and switching mode power circuits, such as USB splitters, peripheral shields, and multi-channel DC/DC converters. In addition, it is used to regulate the current output of a battery management scheme.

The UDN2987A-6-T is a versatile power device that can be used in a variety of applications, ranging from low-voltage (3.3V) to high-voltage (18V) DC motors, and from high-current switching mode power supplies to low-current LED drivers. The device is also well-suited for a wide range of temperature, humidity, and voltage ranges, making it an ideal choice for a variety of industrial and consumer applications.

The UDN2987A-6-T includes six independent power distribution switches, each capable of driving up to 100mA of current. When enabled, each switch will drive an associated output. The switches can be individually configured to operate in either an active-low or active-high mode, depending on the particular application. The output of each switch can be synchronously controlled via an external PWM input, allowing for a high degree of flexibility. In addition, the device includes an additional “global” PWM input that can be used to synchronously control all six outputs.

The UDN2987A-6-T also includes a current-limiting circuit, which is designed to protect the load from over-current. The current limit level can be adjusted through an external resistor, and is enabled via an internal pin. The current-limiting circuit is also used to protect the device itself from over-current, and can also be used in conjunction with the maximum current indicator pin to indicate when the maximum current output has been reached.

The UDN2987A-6-T also includes advanced thermal protection. The thermal shutdown feature activates if the device’s die temperature exceeds a programmed threshold. This prevents the device from being damaged in case of extreme ambient conditions or from being over-driven. The thermal shutdown feature can be turned off when the temperature falls below the programmed thermal threshold.

In addition, the UDN2987A-6-T includes a wide input voltage range and can operate with input voltages of 2.7V to 18V. This makes it suitable for a wide range of applications, from high-voltage DC motors to low-current LED drivers. The device also includes an automatic shutdown feature to protect the device from over-voltage, over-temperature, and over-current condition.

The UDN2987A-6-T is an ideal solution for applications requiring high-performance, high-current power distribution systems. Its versatile design allows for a wide range of applications, from high-current switching mode power supplies to low-voltage DC motors, and from high-voltage LED drivers to low-current peripherals. In addition, the device’s advanced thermal protection and current-limiting capabilities make it an ideal choice for demanding industrial and consumer applications.
