The LB11967V-TLM-H is a motor driver, controller and power management integrated circuit with advanced features and functions that offer flexibility and high performance throughout the system.

The LB11967V-TLM-H is designed for motor control and power management applications. It is suitable for cooling fans, motors and other power applications. The device includes a high voltage, low-dropout (LDO) linear regulator, a three-channel motor driver, a step-up/down DC-DC converter, a simple analog-to-digital (ADC) converter and several other functions.

The LDO linear regulator includes two independent channels, each with adjustable output voltage from 1.8V to 5.4V. Its output current is sufficient for driving most motors, up to 500mA peak per output. The regulator is also capable of synchronous rectification which reduces the power dissipation of the LDOs.

The three-channel motor driver provides full H-bridge drive circuits with four half bridges, capable of driving motors and other inductive loads up to 5 A per channel. It features a soft-start function with adjustable current limiting and overcurrent protection. The device also includes an overvoltage protection and a thermal protection with adjustable on/off temperature.

The step-up/down DC-DC converter is designed to provide regulated power conversion up to 15V and up to 1 A. It features a wide input voltage range and a power-saving sleep mode. It is suitable for applications such as USB appliance supplies, liquid-crystal displays, air conditioners and other power systems.

The simple analog-to-digital (ADC) converter supports up to 8 channels, featuring 4-level oversampling conversion and an adjustable sample rate from 10 Hz to 42 kHz. It also includes a 10-bit A/D conversion function with an accuracy of ±0.5%.

The device also provides a variety of functions, such as an integrated 6-ch PWM generator, an integrated 3-vt pulse-modulation generator, an internal temperature sensor circuit, watchdog timer and more.

In summary, the LB11967V-TLM-H is an advanced and integrated device that offers high performance and flexibility throughout the motor control and power management system. It is suitable for a wide range of applications including fans, motors, display and other power conversions.
