ATA663232/55

LIN System Basis Chip Including LIN Transceiver, Voltage

Regulator and Wake-Input

Features

General Description

The ATA663232/55 system basis chip is a fully

integrated LIN transceiver, designed according to the

LIN specification 2.0, 2.1, 2.2, 2.2A and SAEJ2602-2,

with a low drop voltage regulator (3.3V/5V/85 mA) and

a high voltage wake-input. The combination of voltage

regulator and bus transceiver makes it possible to

develop simple but powerful nodes in LIN bus systems.

• ISO 26262 Functional Safety Ready

• Supply Voltage up to 40V

• Operating Voltage V_VS= 5V to 28V

• Supply Current

- 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

ATA663232/55 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 guarantee

minimized current consumption even in the case of a

floating or a 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

ATA663255: V_VCC= 5.0V ± 2%

ATA663232: V_VCC= 3.3V ± 2%

The voltage regulator is a fully integrated low drop

voltage regulator, with 5V/3.3V 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.

- Sleep Mode: VCC Is Switched Off

• VCC Undervoltage Detection with Internal Reset

(NRES_int)

• Voltage Regulator Is Short Circuit and

Overtemperature Protected

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.

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

2.2A and SAEJ2602-2

• Wake-Up Capability via LIN Bus (100 μs

Dominant) and WKin Pin (100 μs Low Level)

• Wake-Up Source Recognition

• TXD Time-Out Timer

Package Type

• Bus Pin Is Overtemperature and Short Circuit

Protected versus GND and Battery
