4 / 362 page  4 4921C–AUTO–01/07 ATA6602/ATA6603 3. LIN System-basis-chip Block 3.1 Features • Supply Voltage up to 40V • Operating Voltage V S = 5V to 18V • Slew Rate Control According to LIN Specification 2.0 • Supply Current During Sleep Mode Typically 10 µA • Supply Current in Silent Mode Typically 40 µA • Linear Low-drop Voltage Regulator: – Normal Mode: V DD = 5V ±2%/50 mA – Silent Mode: V DD = 5V ±7%/50 mA – Sleep Mode: VDD is Switched Off • V DD Undervoltage Detection (10 ms Reset Time) and Watchdog Reset Logically Combined at Output NRES • Possibility of Boosting the Voltage Regulator with an External NPN Transistor • LIN Physical Layer According to LIN Specification 2.0 • Wake-up Capability via LIN Bus or WAKE Pin • Wake-up Recognition • TXD Time-out Timer • Debug Mode Watchdog Is Switched Off • 60V Load Dump Protection at LIN Pin • Bus Pin is Overtemperature and Short Circuit Protected versus GND and Battery • Adjustable Watchdog Time via External Resistor • Positive and Negative Trigger Input for Watchdog • 5V CMOS Compatible I/O Pins to MCU • Analog Temperature Monitor Output • High EMC and ESD Level 3.2 Description The LIN-SBC is a fully integrated LIN transceiver, complying with the LIN specification, and with a low-drop voltage regulator for 5V/50 mA output and a window watchdog adjustable via an external resistor. The voltage regulator is able to source 50 mA at V S = 18V even at an ambient temperature of 105°C. The output current of the regulator can be boosted by using an external NPN transistor. This combination makes it possible to develop simple, but powerful and cheap, slave nodes in LIN bus systems. LIN-SBC is designed to handle the low speed data communica- tion in vehicles, for example, in convenience electronics. Improved slope control at the LIN driver ensures secure data communication up to 20 kBaud. The bus output is capable of withstanding 60V. Sleep Mode and Silent Mode guarantee a very low current consumption. |
