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.
