Technical Data

LIN system basis chip with dc motor

pre-driver and current sense

33912

The 33912G5/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 33912 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 which can be

disabled for higher data rates.

SYSTEM BASIS CHIP WITH LIN

2^NDGENERATION

Two 50 mA/60 mA high-side switches and two 150 mA/160 mA low-side

switches with output protection are available. 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.

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).

AC SUFFIX (Pb-FREE)

98ASH70029A

32-PIN LQFP

The 33912 is compatible with LIN Protocol Specification 2.0, 2.1, and SAEJ2602-

2. This device is powered using SMARTMOS technology.
