LIN System Basis Chip with DC

Motor Pre-driver and Current

Sense

33912

The 33912 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 33912 has a 5.0V - 60mA 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 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 and two 160mA low side switches

with output protection are available for driving resistive and inductive

loads. All outputs can be pulse-width modulated (PWM). Four high

voltage inputs are available for use in contact monitoring, or as external

wake-up inputs. These inputs can be used as high voltage Analog

Inputs. The voltage on these pins is divided by a selectable ratio and

available via an analog multiplexer.

AC SUFFIX (Pb-FREE)

98ASH70029A

The 33912 has three main operating modes: Normal (all functions

available), Sleep (V_DDoff, wake-up via LIN, wake-up inputs (L1-L4),

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

current capability, wake-up via CS, LIN bus, wake-up inputs, cyclic

sense, forced wake-up and external reset).

32-PIN LQFP

The 33912 is compatible with LIN Protocol Specification 2.0.
