LIN System Basis Chip with High Side Drivers

The 33910G5/BAC is a Serial Peripheral Interface (SPI) controlled System Basis Chip (SBC), combining many frequently used functions in an MCU based system, plus a Local Interconnect Network (LIN) transceiver. The 33910 has a 5.0 V, 50 mA/60 mA low dropout regulator with full protection and reporting features. The device provides full SPI readable diagnostics and a selectable timing watchdog for detecting errant operation. The LIN Protocol Specification 2.0 and 2.1 compliant LIN transceiver has waveshaping circuitry that can be disabled for higher data rates.

Two 50 mA/60 mA high side switches with optional pulse-width modulated (PWM) are implemented to drive small loads. One high voltage input is available for use in contact monitoring, or as external wake-up input. This input can be used as high voltage Analog Input. The voltage on this pin is divided by a selectable ratio and available via an analog multiplexer.
