Power Management ICs (PMICs) are the perfect solution for power system design and control. They provide a variety of features to enable intelligent control and efficient operation. PMICs come in many forms, but they all have the same basic purpose – to provide efficient, reliable power conversion and control.

Supervisors are a type of PMIC that are designed to monitor system conditions and take appropriate action as needed to ensure stable and reliable operation. One of the most popular families of PMIC supervisors is the LM3704XDBP-232. This family of supervisors provides a range of features for intelligent system control and current/voltage regulation.

Application Field

The LM3704XDBP-232 supervisors are designed to be used in mobile power systems. These systems are designed to meet the demands of mobile applications such as laptop computers, tablets, smartphones, and other portable electronic devices. These systems are typically powered by lithium-ion batteries and require precise voltage and current regulation throughout the system.

The LM3704XDBP-232 supervisors are designed to meet the needs of these systems by providing overvoltage protection, reverse current protection, current-limiting, thermal management, system monitor, and low-power operation. These features enable precise control of system power and enable longer run-times from a single battery charge.

Working Principle

The LM3704XDBP-232 supervisors are based on a pulse-width modulation (PWM) method of power control. This method works by rapidly switching the output voltage at a set frequency, and modulating the duty cycle of the pulses to achieve the desired output voltage and current. The LM3704XDBP-232 supervisors provide an adjustable output voltage range of 0.8V to 2.4V, and a maximum output current of 6A. The PWM frequency is adjustable from 200kHz to 1MHz, allowing the user to optimize the performance of the system based on requirements.

The LM3704XDBP-232 also provides system monitoring and protection features. These include overvoltage protection, reverse current protection, current-limiting, and thermal management. These features ensure stable and reliable performance in mobile applications and protect the system from damage due to overvoltage, reverse current, or excess heat.

In addition, the LM3704XDBP-232 supervisors offer a low-power operating mode to conserve battery power in applications that require prolonged run times. The low-power operation mode reduces the PWM switching and output current to minimize power consumption. This mode allows the system to run for longer durations without needing to recharge the battery, enabling longer run times from a single charge.

The LM3704XDBP-232 supervisors are ideal for mobile power systems. They provide a range of features to enable precise control and protection of the system, and the low-power operation mode extends run times from a single battery charge. This makes the LM3704XDBP-232 an ideal choice for mobile applications such as laptops, tablets, and smartphones.
