AMIS-40616
LIN Transceiver with 5V Voltage Regulator
Data Sheet
1.0 General Description
The AMIS-40616 is a full-featured local interconnect network (LIN) transceiver designed to interface between a LIN protocol controller
and the physical bus. The transceiver is implemented in AMI Semiconductor’s SmartPower, high-voltage, mixed-signal 0.35µm CMOS
technology enabling both high-voltage analog circuitry and digital functionality to co-exist on the same chip.
The AMIS-40616 LIN device is a member of AMI Semiconductor’s in-vehicle networking (IVN) transceiver family and integrates a LIN
v2.0 physical transceiver and a 5V voltage regulator. It is designed to work in harsh automotive environments and is certified to the
TS16949 qualification flow.
The LIN bus is designed to communicate low rate data from control devices such as door locks, mirrors, car seats, and sunroofs at the
lowest possible cost. The bus is designed to eliminate as much wiring as possible and is implemented using a single wire in each node.
2.0 Key Features
2.1 LIN-Bus Transceiver
• LIN compliant to specification revision 2.0 (backwards compatible to version 1.3) and J2602
• SmartPower, high-voltage, mixed-signal 0.35µ CMOS technology
• Bus voltage ± 45V
• Transmission rate up to 20kBaud
• SOIC 14 Green package
2.2 Protection
• Thermal shutdown
• Indefinite short-circuit protection of pins LIN and WAKE to supply and ground
• Load dump protection (45V)
• Bus pins protected against transients in an automotive environment
• ESD protection level for LIN, INH, WAKE, and Vbb up to ±8kV

2.3 EMI Compatibility
• Integrated slope control
2.4 Voltage Regulator
• Output voltage 5V / ~50mA
• Wake-up input
• Enable inputs for stand-by and sleep mode
• INH output for auxiliary purposes (switching of an external pull-up or resistive divider towards battery, control of an external voltage
regulator etc.)
2.5 Modes
• Normal mode: LIN communication with either low (up to 10kBaud) or normal slope
• Sleep mode: VCC is switched “off” and no communication on LIN bus
• Stand-by mode: VCC is switched “on” but there is no communication on LIN bus
• Wake-up bringing the component from sleep mode into standby mode is possible either by LIN command or digital input signal on
WAKE pin. Wake-up from LIN bus can also be detected and flagged when the chip is already in standby mode.

Notes:
1. The AC parameters are specified for following RC loads on the LIN bus: L1 = 1kΩ / 1nF; L2 = 660Ω / 6.8nF; L3 = 500Ω / 10nF.
2. Low slope mode is not compliant to the LIN 1.3 or LIN 2.0 standard.
