描述
The TPS92662-Q1 LED matrix manager device enables fully dynamic adaptive lighting solutions by providing individual pixel-level LED control.
The device includes four sub-strings of three series-connected integrated switches for bypassing individual LEDs. The individual sub-strings allows the device to accept either single or multiple current sources, as well as paralleling up to four switches for bypassing high current LEDs.
The device contains a multi-drop universal asynchronous receiver transmitter (UART) serial interface for control and management by a master microcontroller. The serial interface supports the use of CAN transceivers for a more robust physical layer. The I2C communication interface can be used to read from and write to an external EEPROM that can store system calibration data.
An on-board 8-bit ADC with two multiplexed inputs can be used for system temperature compensation such as binning and coding.
The internal charge pump rail that can float up to 69 V above GND provides the LED bypass switch gate drive supply. The low on-resistance (RDS(on)) of the bypass switch minimizes conduction loss and power dissipation.
The phase-shift and pulse-width are programmable for each individual LED in the string. The PWM frequency is adjustable via an internal register and multiple devices can be synchronized. In addition, the switch transitions during PWM dimming operation have a programmable slew rate limit to mitigate EMI concerns.
The device features open LED protection with programmable threshold as well as open and short LED fault reporting via the serial interface.
