Description

The L6362 is a monolithic dual push pull

Transceiver fully compliant to PHY2 (3 wires)

supporting COM1 (4.8 kbaud), COM2 (38.4

kbaud) and COM3 (230.4 kbaud) modes. C/Q and

I/Q output stages are programmable: high-side,

low-side or push-pull; also cut-off current and cut-

off current delay time are programmable. Cut-off

current and cut-off current delay time combined

with thermal shutdown and automatic re-start

protect the device against overload and short

circuit. C/Q and I/Q output stages are able to drive

also inductive loads up to 10 mJ. Supply voltage

is monitored and low voltage condition is

detected. L6362 transfers/receives, through the

PHY2, data received/transmitted in the digital

block from sensor/actuator to/from the L6360 twin

device. To enable full IC control, regarding

configuration and monitoring (i.e. fault condition

stored in the status register) the communication

between the system microcontroller and L6362 is

based on a high speed 2 wires interface. The

L6362 has nine registers to manage the

programmable parameters and the status of the

IC. Monitored fault conditions are: Power On (L+

line), Overtemperature, C/Q overload, I/Q

overload, linear regulator under-voltage and parity

check. The fully integrated high precision

oscillator, requiring an external resistor, provides

internal clock as well as system clock Internal

LED driver blocks, in open drain configuration,

provide two programmable sequences to drive

two LEDs. The integrated, high efficiency low

power Step-down switching converter provides

power supply to the IC and external circuits.
