概述
The TPM8909Q is a 16-channel, high-speed half-bridge driver IC, capable of handling 80V and providing up to 1A per channel. Engineered for the control of capacitor arrays in VCSEL driver circuits, it is pivotal in the operation of solid-state LiDAR systems.
In the field of LiDAR, the generation of short, highpower pulses is critical. The VCSEL array, known for its robustness and cost efficiency, excels in applications requiring blind-spot detection in LiDAR technology. The TPM8909Q utilizes capacitor arrays to efficiently store and manage the energy required for these pulses. By charging capacitors of specific channels, it enables precise and controllable VCSEL output, ensuring the system's accuracy and responsiveness in high-resolution LiDAR applications.
The TPM8909Q features a high-speed 4-to-16 multiplexer for directing energy to specific channels, with the ability to tri-state or pull down non-selected channels based on operational mode. It uses an external resistor to precisely control the maximum current to each channel, up to a capacity of 1A. For channels in the discharge phase, internal current limiting is in place to mitigate the risk of excessive current during switching. The device is equipped with voltage indicators to monitor charge and residual voltage levels for safety and system performance. Additionally, it includes an open-drain fault output and a diagnostics enable input for fault detection and management.
