| BUS IC K-Bus transceiver LIN- / K-Bus transceiver y LIN transceiver + VREG LIN transceiver LIN transceiver + VREG + WD Single wire CAN transceiver CAN transceiver DC/DC CONVERTER MOTOR DRIVER IC RIPPLE COUNTER DRIVER IC I/O IC SENSOR IC SENSOR INTERFACE IC y LIN transceiver with voltage regulator FEATURES y y y y y y y y Supply voltage range VS 5.25V to 18V LIN-Bus transceiver, up to 20kBaud Output driver with slewrate control Very low standby current (<30A typical) Bus input voltage range from - 24V to + 30V (independent of VS) Wake up function via bus Regulator output voltage 5V, 1.5%, 100mA, current limitation Reset with two reset times (15ms and 100ms) and two reset levels: E910.18: 3.15V and 4.65V E910.45: 3.15V and 3.95V y y y y y Undervoltage recognition, fixed threshold at typ. 7.3V Over temperature protection Universal comparator with high voltage input - 40C to + 125C operating temperature SO16w package Two versions of this IC with different reset levels are available: E910.18: 3.15V / 4.65V and E910.45: 3.15V / 3.95V The over temperature protection disables the voltage regulator and the bus driver. After return to normal operation conditions a reset function will be generated. For sensor applications only these two ICs are needed. Even the sensor supply can be done as a rule with the integrated 100mA VDD regulator. DESCRIPTION The IC is designed for LIN slave applications. The microcontroller is completely protected from the harsh automotive environment.
