Power management integrated circuits (PMICs) are commonly used to manage electricity and ensure efficient power delivery in microprocessor-based systems. They have the ability to monitor, control and regulate basic electronic functions, such as voltage, current and temperature. PMICs control the delivery of power in an efficient and reliable way, ensuring longer battery life and better performance from the hardware. One example of such a PMIC is the ISL58797CRTZ-T13, which is a laser driver for the generation of output light pulses for laser projection systems. This article examines the application field and working principle of the ISL58797CRTZ-T13, and how it differs from other PMIC products.

The ISL58797CRTZ-T13 is designed to drive laser emitters in a wide variety of technologies, including LCoS, MEMS, SPECTRA and surface emitting laser diodes. It is used in laser projection systems, such as the one found in mobile phones and projectors, to generate high-quality visible light with a high degree of efficiency. The ISL58797CRTZ-T13 provides a cost-effective solution for these types of applications, allowing for higher efficiency and longer projection lifetimes. The laser driver integrates an adaptive transconductance amplifier-based modulation, which reduces power and energy consumption, resulting in an improved projection output.

The ISL58797CRTZ-T13 is capable of driving up to 6 laser emitters through its 6 channels. Each channel can be individually configured for a broad range of data rates, from tens of kilohertz to several hundred MHz. The CAN bus interface enables the IC to receive and transmit information to the host device, while an integrated digital potentiometer is used to adjust the output current of each channel. The IC is package in a 25 PQFN housing and operates over a wide temperature range, making it suitable for use in a variety of applications.

The ISL58797CRTZ-T13 works by producing an electric current that passes through the laser emitter. This electric current is modulated using an adaptive transconductance amplifier-based modulation technique, which allows the laser current to be modulated at different levels of brightness. This allows the laser to emit light of different intensity, creating a more dynamic and lifelike projection output. The modulation also reduces energy and power consumption, prolonging the lifespan of the projection system. The IC also includes several safety features, including short-circuit protection and thermal management, which help to prevent damage to the system.

The ISL58797CRTZ-T13 is ideal for use in a variety of laser projection systems. It is an affordable, small and efficient laser driver, offering superior performance and reliability. Its adaptive transconductance amplifier-based modulation helps to reduce power and energy usage, while the integrated safety features help to keep the system safe from any damage. Overall, the ISL58797CRTZ-T13 is an excellent PMIC for use in laser projection systems, providing a cost-effective and reliable solution.
