Shenzhen Meiyuxin Technology Co., Ltd. [Automotive Chip Distributor] Supply TPS92662AQPHPRQ1 LED Matrix Manager! ! !

Product Description:

The TPS92662AQPHPRQ1 LED matrix manager device enables fully dynamic adaptive lighting solutions by providing individual pixel-level LED control. The device's 3 series integrated switches have 4 substrings each, bypassing a single LED. Individual substrings allow the device to accept single or multiple current sources.

The TPS92662AQPHPRQ1 is a programmable Pierce crystal oscillator driver that achieves optimum performance by selecting the driver strength as recommended by the quartz crystal or ceramic resonator manufacturer. It also includes a clock buffer with selectable drive strength. By changing the drive strength of the clock buffer, the rise and fall times of the clock signal and EMI can be controlled. The clock buffer can be disabled if necessary to remove noise from the clock signal and minimize EMI.

The TPS92662AQPHPRQ1 supports a multidrop Universal Asynchronous Receiver Transmitter (UART) serial interface and is compatible with the TPS92662-Q1 and TPS92663-Q1 devices. The I2C communication interface is used to read data from and write data to an external EEPROM that stores system calibration data.

An onboard 8-bit ADC with two multiplexed inputs can be used for system temperature compensation and to measure binning values for LED binning and encoding.

An internal charge pump rail provides the gate drive voltage for the LED bypass switch. The low resistance (RDS(on)) of the bypass switch minimizes conduction losses and power dissipation.

The TPS92662AQPHPRQ1 both have the same register settings, which can be used to program the phase shift and pulse width of individual LEDs in the string and to report LED open and short faults.
