LIN System Basis Chip with

2x60mA High Side Drivers

33910

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.

SYSTEM BASIS CHIP WITH LIN

2^NDGENERATION

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.

The 33910 has three main operating modes: Normal (all functions

available); Sleep (V_DDoff, wake-up via LIN, wake-up input (L1), cyclic

sense and forced wake-up) and Stop (V_DDon with limited current

capability, wake-up via CS, LIN bus, wake-up input, cyclic sense,

forced wake-up and external reset).
