Voltage Regulator with Integrated LIN Transceiver

ON Semiconductor 

NCV7361A

If the application does not need the wake−up capability

of the NCV7361A, a direct connection EN to VSUP is

possible. In this case, the NCV7361A operates in

permanent normal mode. Also possible is the external

(outside of the module) control of the EN line via a VBAT

signal.

Wake−Up

If the regulator is in a standby (sleep) mode, it can be

woken up with the BUS interface. Every pulse on the BUS

(high pulse or low pulse) with a pulse width of minimum

25 ms switches on the regulator.

After the BUS wake−up for the regulator, it can only be

turned off with a high level followed by a low level on the

EN pin.

Overtemperature Shutdown

The thermal shutdown threshold is 155°C < TJ < 175°C.

When exceeded, the overtemperature shutdown will be

active and the regulator voltage will be switched off. VOUT

drops down, the reset state is entered and the

bus−transceiver is switched off (recessive state).

After TJ falls below 140°C, the NCV7361A will be

initialized (see Figure 17), independent from the voltage

levels on EN and BUS. Within the thermal shutdown mode,

the transceiver can’t be switched to the normal mode with

local or with remote wake−up.

Function of the NCV7361A is possible between TAmax

(125°C) and the switch−off temperature, but small

parameter differences can appear.

After overtemperature switch−off the IC behaves as

described in the RESET chapter.
