The AS1109-BSOT is a high-performance 8-channel low-side shift register and latch driver that is ideal for LED lighting applications. It features integrated drive transistors, which allow for easy and efficient switching between individual channels. The device offers load current up to 400mA, as well as ultra-low power consumption, providing excellent performance for LED control applications. Additionally, the AS1109-BSOT has a noise rejection filter for low EMI operation and a thermal overload protection circuit for improved system reliability.

The AS1109-BSOT is a cost-effective, highly efficient LED driver specifically designed for automotive and industrial lighting applications. This device is comprised of an 8-channel power MOSFET low-side switch and a latch, both of which can be controlled using either a single enable/disable pin or individual enable/disable pins, depending on the particular application. The 8 channels are switched independently and enable either a single LED per channel or multiple strings of LEDs in series, making the AS1109-BSOT suitable for a wide range of LED lighting applications.

The AS1109-BSOT is comprised of an advanced power management IC (PMIC) and a low-side MOSFET switch. The PMIC contains the necessary logic to monitor the load current, monitor the voltage drop across the MOSFET, and regulate the output voltage. The PMIC also features thermal overload protection and two PWM selectable current limit modes to reduce the amount of energy consumed by the device. Additionally, the PMIC contains a noise rejection filter to reduce EMI and improve system reliability.

The low-side switch is configured with a P-channel MOSFET, allowing for a low on-resistance of only 1 ohm. This significantly reduces the amount of power consumed by the device, as well as the heat generated by the device, allowing for higher efficiency applications. The device also features a logic-controlled enable input, which permits the device to be switched on and off with minimal effort, making it especially suitable for automotive applications.

The AS1109-BSOT is an ideal solution for LED lighting applications that require multiple channels of LED control, and a low power consumption. The combination of an 8-channel low-side shift register and latch driver, a power management IC and a MOSFET switch, allow for a highly efficient, cost-effective and reliable LED driver solution.
