The TPS99000-Q1 system management and illumination controller is part of the DLP553x-Q1 and DLP462x-Q1 chipset, which also includes the DLPC23x-Q1 DMD display controller. The chipset provides all functions needed to support and exceed typical 5000:1 display dimming requirements for Head-Up Display (HUD) applications, with typical requirements of 3 nits to 15,000 nits brightness range and tight color point control. An integrated DMD high-voltage regulator supplies DMD mirror reference voltages, meeting the required tight tolerances. The power supply sequencer and monitor provide robust coordination of power-up and power-down events for the entire chipset.
The TPS99000-Q1 illumination 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 illumination control system. The ADC is capable of automatic sampling up to 63 events per video frame.
Advanced system status monitoring circuits provide real-time visibility into display sub-system operational condition, including two processor watchdog circuits, two die temperature monitors, comprehensive supply monitoring for overvoltage and undervoltage detection, checksum and password register protection with byte-level parity on SPI bus transactions, an excessive brightness monitor circuit, and other built-in test functions.
