MC33910G5AC/MC3433910G5AC NXP Semiconductors Document Number: MC33911 Rev. 10.0, 7/2016 Technical Data LIN system basis chip with DC motor 33911 pre-driver The 33911G5/BAC is a SMARTMOS 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 33911 SYSTEM BASIS CHIP WITH LIN 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. One 50 mA/60 mA high-side switch and two 150 mA/160 mA low-side switches with output protection are available. All outputs can be pulse-width modulated (PWM). Two 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 33911 has three main operating modes: Normal (all functions available), AC SUFFIX (Pb-FREE) Sleep (V off, wake-up via LIN, wake-up inputs (L1, L2), cyclic sense, and 98ASH70029A DD 32-PIN LQFP forced wake-up), and Stop (V on with limited current capability, wake-up via DD CS, LIN bus, wake-up inputs, cyclic sense, forced wake-up, and external reset). The 33911 is compatible with LIN Protocol Specification 2.0, 2.1, and SAEJ2602-2.
