Operating conditions

2.1

Operating range

This part may not operate if taken outside the operating range. Once the condition is

returned within the specified maximum rating or the power is recycled, the part will recover

with no damage or degradation.

2.1.1

Functional operative range

4.5 V ≤ Vbat ≤ 18 V (-40 °C ≤ Tj ≤ 150 °C);

All the electrical capabilities are guaranteed by characterization as reported in Section 3:

Electrical performance characteristics.

2.1.2

Jump start conditions

18 V ≤ Vbat ≤ 27 V (-40 °C ≤ Tj ≤ 150 °C);

Operation at Jump start condition for a maximum duration of 1 minute.

All ouputs are switched according to the commands on the SPI bus or the PWM inputs. The

SPI bus and the inputs are functional during the Jump-Start condition.

The over-temperature shutdown and over current protection of the device are not

guaranteed to stay functional for Vbat between 18 V and 27 V.

The reliability and the functionality of the L9733XP are not compromised when the Jump-

Start condition is not repeated for more than five times.
