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.
Two 60mA high side switches with optional pulse-width modulation
www.DataShee(tP4UW.cMo)mare 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 (VDD off, wake-up via LIN, wake-up input (L1), cyclic
sense and forced wake-up) and Stop (VDD on with limited current
capability, wake-up via CS, LIN bus, wake-up input, cyclic sense,
forced wake-up and external reset).
The 33910 is compatible with LIN Protocol Specification 2.0.
