The AL5873Q is an automotive-compliant three-channel linear LED driver with PWM dimming and analog dimming control. Each channel can drive up to 250mA with a combined driving current up to 750mA. All three LED channels’ current of the AL5873Q are set by two reference resistors connected to the REF1 and REF2 pin. The AL5873Q regulates LED current for each channel, accurate down to ±4%, with excellent dimming performance. The AL5873Q enters standby mode to save power if no PWM signal is detected.
The AL5873Q monitors the temperature and reduces the LED current if its juncture temperature exceeds the threshold temperature. For improved system robustness the AL5783Q has input under voltage lock-out (UVLO), LED string-open /-short protection, and overtemperature protection (OTP) which are reported by a fault indicator (FAULTB) pin. The AL5873Q is available in TSSOP-16EP (Type DX) package.

The PI4IOESV6416Q is a 16-bit general-purpose I/O expander that provides remote I/O expansion for most microcontroller families via the l2C-bus interface.
It provides a simple solution when additional I/Os are needed while keeping interconnections to a minimum, for example, in battery-powered mobile applications for interfacing to sensors, push buttons, keypad, etc.
It can operate from 1.65 V to 5.5 V on the GPIO-port side and 1.65V to 5.5V on the SDA/SCL side. This allows the PI4IOE5V6416Q to interface with next generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power.
The bidirectional voltage-level translation in the PI4IOE5V6416Q is provided through VDD (I2C_bus). VDD (I2C_bus) should be connected to the VDD of the external SCL/SDA lines. The voltage level on the GPIO-port of the PI4IOE5V6416Q is determined by VDD(P).
At power on, the I/Os are configured as inputs; however, the system master can enable the I/Os as either inputs or outputs by writing to the I/O direction bits. The data for each input or output is kept in the corresponding Input or Output register. All registers can be read by the system master.
PI4IOESV6416Q has open-drain interrupt (INT) output pin that goes LOW when the input state of a GPIO-port changes from the input-state default register value. The device also has an interrupt masking feature by which the user can mask the interrupt from an individual GPIO port.

The PI4IOE5V6534Q is a 34bit general-purpose I/O expander that provides remote I/O expansion for most microcontroller families via the FC-bus interface.
The device provides a simple solution when additional I/Os are needed while keeping interconnections to a minimum. for example, in battery-powered mobile applications for interfacing to sensors, push buttons, keypad, etc.
The expander IC can operate from 1.65V to 5.5V on the GPIO-port side and 0.8V to 3.6V on the SDA/SCL side. This allows the PI4IOE5V6534Q to interface with next generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power.

The PI2DPX1217 is a non-blocking USB Type-C® DP-Alt mode linear ReDriver™ in 4-to-4 configuration operated by 1.8v power supply. It supports four operation modes through I2C bus setting for USB3.2 Gen2, USB3.2 Gen2/2-lane DP1.4/DP2.0 (UHBR10), 4-lane DP1.4/ DP2.0 (UHBR10) or USB3.2 Gen2x2 with speed up to 10Gbps per channel. It swaps the high speed channels under the flip and non-flip plug in compliance to Type-C connector with the integrated AUX crossbar switch for SBU pins. The non-blocking linear Redriver design ensures the differential signals conveying pre-shoot and de-emphasis equalization waveforms from transmitter side to receiver side, this can help to optimize the overall channel link adjustment conducted by the system transmitter and receiver with DFE. The CTLE equalizers are implemented at the inputs of the Redriver to compensate the channel loss and reduce the ISI jitters. The programmable flat gain and linearity adjustments support the eye diagram opening. The CTLE EQ gains, flat gains and linearity are individually programmable on each channel for flexible tuning via I2C register settings. USB channel by-pass mode is initialized at power-on as default mode to support factory setting especially for the system with only Type-C connector.
