System Basis Chip with LIN Transceiver
The 33689 is a SPI-controlled System Basis Chip (SBC) that combines many frequently used functions in an MCU-based system plus a Local Interconnect Network (LIN) transceiver.
Applications include power window, mirror, and seat controls.
The 33689 has a 5.
0 V, 50 mA low dropout
regulator with full protection and reporting features.
The device provide full SPI-readable diagnostics and a selectable timing watchdog for detecting errant operation.
The LIN transceiver waveshaping circuitry can be disabled for higher data rates.
One 50 mA and two 150 mA high...
