TPS99000-Q1 - DLP® System Management and Illumination Controller for DLP553x-Q1 Chipset

The TPS99000-Q1 system management andillumination controller is part of the DLP553x-Q1 chipset,which also includes the DLPC230-Q1 DMD display controller. Thechipset provides all functions needed to support and exceed typical 5000:1 display dimmingrequirements for Head-Up Display (HUD) applications, with typical requirements of 3 to 15,000 nitsbrightness range and tight color point control.

An integrated DMD high-voltage regulator supplies DMD mirror reference voltages, meetingthe required tight tolerances. The power supply sequencer and monitor provide robust coordinationof power-up and power-down events for the entire chipset.

The TPS99000-Q1 illuminationcontroller integrates a 12-bit ADC, two DACs (12-bit and10-bit), and two high-performance photodiode signal conditioning transimpedance amplifiers(TIAs) as the core components of theillumination control system. The ADC is capable ofautomatic sampling up to 63 events per video frame.

Advanced system status monitoring circuits provide real-time visibility into displaysub-system operational condition, including two processor watchdog circuits, two die temperaturemonitors, comprehensive supply monitoring for overvoltage and undervoltage detection, checksum andpassword register protection with byte-level parity on SPI bus transactions,an excessive brightness monitor circuit, and other built-intest functions.
