Shenzhen Meiyuxin Technology Co., Ltd. TI channel stock] Supply TPS9900TPZPRQ1 DLP® system management and lighting controller for DLP553x-Q1 chipset Quality assurance New original! ! !

Product Description:

The TPS9900TPZPRQ1 system management and lighting controller is part of the DLP553x-Q1 chipset, which also includes the DLPC230-Q1 DMD display controller. With brightness requirements ranging from typically 3 to 15,000 nits and tight color point control, the chipset provides all the features needed to support head-up display (HUD) applications and exceed the dimming requirements of typical 5000:1 displays .

The TPS9900TPZPRQ1 integrated DMD high-voltage regulator power supply provides a DMD mirrored reference voltage that meets tight tolerance requirements. Power sequencers and supervisors provide reliable coordination of power-up and power-down events across the chipset.

The TPS9900TPZPRQ1 lighting controller integrates a 12-bit ADC, two DACs (12-bit and 10-bit), and two high-performance photodiode signal conditioning and a transimpedance amplifier (TIA), one of the core components of a lighting control system. The ADC is capable of automatically sampling up to 63 events per video frame.

Advanced system status monitoring circuitry provides real-time graphics to show subsystem operation, including two processor watchdog circuits, two die temperature monitors, comprehensive power supply monitoring for overvoltage and undervoltage detection, Checksum and password register protection with byte-level parity on SPI bus transactions, highlight monitor circuitry, and other built-in test functions.
