Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Product Description:

The TPS99000x-Q1 system management and Lighting controller is part of the DLP553x-Q1 chipset, which also includes the DLPC230x-Q1 DMD display controller. The chipset has all the features needed to support and exceed the 5000:1 display dimming requirements typical of head-up display (HUD) applications, which typically require a 3-1500nit brightness range and fine color point control. The integrated DMD high voltage regulator provides a DMD mirror reference voltage to meet the required tight tolerances. The power sequencer and monitor robustly coordinate power on and power off events for the entire chipset.

The TPS99000x-Q1 lighting controller integrates a 12-bit ADC, two Dacs (12-bit and 10-bit), and two high-performance photodiode signal conditioning transimpedance amplifiers (TIAs) as the core components of the lighting control system. The ADC is capable of automatically sampling up to 63 events per video frame. The advanced system status monitoring circuit can observe and display the operation of the subsystem in real time. These include two processor watchdog circuits, two bare chip temperature monitors, comprehensive power monitoring for overvoltage and undervoltage detection, check and password register protection (byte level parity on SPI bus transactions), overlight monitoring circuits, and other built-in test functions.
