The AT9932TS-G is a Programmable Multi-Channel LED Driver which is designed as a PMIC - LED Drivers. It is a highly integrated, cost-effective product that provides an optimal solution for multi-channel LED driving applications.

The AT9932TS-G is a two-component, two-power product consisting of an independent power stage and control module. The power stage supplies up to 8 sequential channels of output current, adjustable up to 150mA, with a slew rate capable of up to 20Khz. The control module contains up to 8 independent dimming control channels providing precise, high-resolution dimming control. The device can be used for low voltage applications with an input voltage range of 2.5V to 5.5V.

AT9932TS-G has a wide range of applications, from automotive (headlight, brake light, and backlight), to consumer and commercial LED lighting such as strips, family lighting, street lighting, mobile phone backlight, medical and signage lighting. It can also be used in instrumentation and measurement applications.

The chosen LED driving solution for the application will depend on certain factors including the number of current channels needed, the operating voltage, and the required dimming resolution. In addition, the AT9932TS-G has two working modes, constant current and constant voltage. In constant current mode, the LED can be adjusted and dimmed by setting the current level. In constant voltage mode, the LED can be adjusted and dimmed via a simple PWM signal.

The AT9932TS-G has a few features that make it stand out from competing LED driver products. One such feature is the adjustable current slew rate, which can be set to fit the LED current sources. This feature allows the user to balance between accuracy and power consumption. The other unique feature is the precision dimming control, which provides accurate dimming control over the full operating temperature range.

The device also has protections in place for current leakage, open output, and over-current conditions. The protection limits can be programmed to minimize the risk of damage to the device and its connected LEDs. In addition, the LEDs can be connected in series or in parallel, depending on the existing system architecture.

The AT9932TS-G is an innovative and highly efficient LED driver solution that provides improved efficiency, accuracy, and flexibility. It is an ideal solution for multi-channel LED lighting applications where precise, reliable dimming control is required.
