ATA663201/03/31/54

LIN Bus Device Family Including Voltage Regulator and LIN SBC

with Compatible Footprint

Features

Description

• ISO 26262 Functional Safety Ready

• Supply Voltage up to 40V

• Operating Voltage V_VS= 5V to 28V

• Supply Current

The ATA663201/03/31/54 device family includes two

basic products: a LIN system basis chip (SBC) and a

low-drop voltage regulator with compatible footprints.

The ATA663231/54 (SBC) is a fully-integrated LIN

transceiver, designed according to the LIN

specification 2.0, 2.1, 2.2, 2.2A, ISO 17987-4 and

SAEJ2602-2, with a low-drop voltage regulator (3.3V/

5V/85 mA). The combination of voltage regulator and

bus transceiver makes it possible to develop simple but

powerful nodes in LIN bus systems.

- Sleep mode: typically 9 μA

- Silent mode: typically 47 μA

- Very low current consumption at low supply

voltages (2V < V_VS< 5.5V): typically 130 μA

• Linear Low-Drop Voltage Regulator, 85 mA

Current Capability:

The ATA663231/54 is designed to handle the low-

speed data communication 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 designed to withstand

high voltage. Sleep mode and Silent mode ensure

minimized current consumption even in the case of a

floating or a short-circuited LIN bus.

- MLC (multi-layer ceramic) capacitor with 0Ω

ESR

- Normal, Fail-Safe and Silent mode

- ATA663254: V_VCC= 5.0V, ±2%

- ATA663231: V_VCC= 3.3V, ±2%

• Sleep Mode: VCC is Switched Off

• Active Mode:

The ATA663201/03 (voltage regulator) is a fully

integrated low-drop voltage regulator, with 3.3V/5V

output voltage and 85 mA current capability. It is

especially designed for the automotive environment. A

key feature is that the current consumption is always

below 170 μA (without load), even if the supply voltage

is below the regulator’s nominal output voltage.

- ATA663203: V_VCC= 5.0V, ±2%

- ATA663201: V_VCC= 3.3V, ±2%

• VCC Undervoltage Detection with Open Drain

Reset Output (NRES, 4 ms Reset Time)

• Voltage Regulator is Short-Circuit and

Overtemperature Protected

• LIN Physical Layer According to LIN 2.0, 2.1, 2.2,

2.2A, ISO 17987-4 and SAEJ2602-2

Note:

The current LIN standards use the

terminology "Master" and "Slave”.

The LIN standard groups have decided

that the terms "Commander" and

"Responder" will be used in future.

• Wake-Up Capability via LIN Bus (100 μs

Dominant)

• Wake-Up Source Recognition

• TXD Time-Out Timer
