Advance Information

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 that

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.

AC SUFFIX (Pb-FREE)

98ASH70029A

32-PIN LQFP

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).

ORDERING INFORMATION

Temperature

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

SAEJ2602-2.
