PMIC Laser Drivers are complex, often customized, devices that are integral parts of larger systems. They are needed to drive lasers, both for industrial applications and light emitting products. An example of a PMIC Laser Driver is the ONET1101LRGETG4. This device is an advanced laser driver for continuous-wave and modulated operation of lasers. It includes both an Ultrafast Rectifier, often referred to as a "Rectifier", and a High-Speed Laser Driver, also known as an "H Driver".

The ONET1101LRGETG4 device has a variety of applications, especially in laser-based products as well as industrial applications that require short pulse widths. Applications of the device include pulse width modulated (PWM) laser driver and red/green/blue (RGB) laser display drivers. Its range of operation extends from -17V to 27V, and it can support pulsed current operation up to 15A.

The ONET1101LRGETG4 operates at up to 100kHz, and it is highly resilient to supply voltage fluctuations, transient noise, and noise produced by other components in the system. It also has advanced EMI (electromagnetic interference) compatibility features that prevent interference from transmitted energy generated by its in-application components. This feature allows for a very high level of safety for those who are close to the laser-driven system.

The ONET1101LRGETG4 operates using a combination of a pulse-width modulator (PWM) and a voltage regulator, as well as several special circuit blocks. The PWM block controls the amount of current that is supplied to the laser diode, while the voltage regulator block provides a stable supply of voltage. The pulse-width modulator block also adjusts the pulse width depending on the characteristics of the laser diode, allowing for optimal performance. Additionally, the ONET1101LRGETG4 integrates a charge pump circuit, which boosts the voltage of the laser diode. This allows the device to drive lasers with higher power ratings.

In addition to its PWM controls, the device also features a digital Monitoring, Protecting and Clearing feature, which allows the user to monitor, protect and clear the laser diode. This allows the device to detect fault conditions and then immediately take corrective actions to protect the device. This ensures that all operations are running at optimal levels, while minimizing risk of damage to the device.

The ONET1101LRGETG4 allows for high speed and high reliability performance, with reliable operation and high efficiency. Additionally, the device is extremely small in size, making it an ideal choice for space-constrained applications. Furthermore, the device offers a wide input voltage range, and it is engineered for use with CMOS and gas lasers, allowing for flexibility with applications.

The ONET1101LRGETG4 is an effective and reliable Laser Driver, offering users excellent performance and reliability. With its advanced EMI compatibility, PWM controls and monitoring, it is a great choice for applications that need high performance and reliability. The device also allows for a wide input voltage range and is engineered for use with CMOS and gas lasers, making the device an ideal solution for laser-based products and industrial applications.
