ATA663331/54
LIN System Basis Chip Including LIN Transceiver, Voltage
Regulator, Dual Low Side Driver and a High Side Switch
Features
Applications
• Supply Voltage up to 40V
• Operating Voltage VVS = 5V to 28V
• Supply Current
• LIN Networks in Automotive
• Industrial
• Medical
• Consumer Applications
- Sleep Mode: Typically 10 μA
- Silent Mode: Typically 47 μA
General Description
- Very Low Current Consumption at Low
Supply Voltages (2V < VVS < 5.5V): Typically
130 μA
Designed in compliance with LIN specifications 2.0,
2.1, 2.2, 2.2A and SAEJ2602-2, the ATA6633XX is a
new generation of system basis chips with a fully
integrated LIN transceiver, a low drop voltage regulator
(3.3V/5V/85 mA), two low side drivers, and one high
side driver. This combination makes it possible to
develop simple, but powerful nodes in LIN bus
systems. ATA6633XX is designed to handle low speed
data communication in vehicles (such as convenience
electronics). Improved slope control at the LIN driver
ensures secure data communication up to 20 kBaud.
The bus output is designed to withstand high voltage.
Sleep mode and Silent mode guarantee minimized
current consumption even in the case of a floating or
short circuited LIN bus.
• Linear Low Drop Voltage Regulator, 85 mA
Current Capability:
- MLC (Multi-Layer Ceramic) Capacitor with
0Ω ESR
- Normal, Fail-Safe and Silent Mode
ATA663354: VVCC = 5.0V ± 2%
ATA663331: VVCC = 3.3V ± 2%
- Sleep Mode: VCC Is Switched Off
• VCC Undervoltage Detection with Open Drain
Reset Output (NRES, 4 ms Reset Time)
• Voltage Regulator Is Short Circuit and
Overtemperature Protected
Note:
The current LIN standards use the
terminology "Master" and "Slave.”
• LIN Physical Layer According to LIN 2.0, 2.1, 2.2,
2.2A and SAEJ2602-2
The LIN standard groups have decided
that the terms "Commander" and
"Responder" will be used in future.
• Bus Pin Is Overtemperature and Short Circuit
Protected versus GND and Battery
• Two Low Side Protected Switches and One High
Side Protected Switch
