LIN System Basis Chip with 2x60mA High Side Drivers
The 33910 is a Serial Peripheral Interface (SPI)-controlled System Basis Chip (SBC), that combines many frequently used functions in an MCU-based system, plus a Local Interconnect Network (LIN) transceiver. It has a 5.0V, 60mA low dropout regulator with full protection and reporting features. The device provides full SPI-readable diagnostic and a selectable timing watchdog for detecting errant operation. The LIN Protocol Specification, version 2.0 compliant LIN transceiver has waveshaping circuitry that can be disabled for higher data rates.
Two 60mA high side switches with optional pulse-width modulation (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 as well. The voltage on this pin is divided by a selectable ratio and available via an analog multiplexer.
