Operating voltage ranges

Table 5. Supply operating ranges summarizes the different operating ranges where different functionalities of the

FlexInput are guaranteed. It is assumed that the junction temperature range for proper functionality goes from

-40 °C up to 150 °C, unless otherwise specified.

Remark

Load Dump

36 – 58

Parameters can be out of tolerance (if RST=’1’), system is not damaged for

pulse duration of 500 ms, 10 time in life.

Jump start

0 – 48

Parameter can be out of tolerance (if RST=’1’), system is not damaged for

pulse duration of 60 s, 10 time in life.

Normal

7.5 – 36

4.85 –

5.15

All parameters in spec. with VDD5_REF = 5 V(1)

Low Batt

5.5 – 7.5

4.85 –

5.15

All parameters in spec. with VDD5_REF = 5 V(1) Current sources can be out

of tolerance, but still non-zero.

Resistance measurement is guaranteed for UBSW-V(IO)>1.5 V that means if

UBSW = 5.5 V → IOx<4 V

Normal, Low

VDD5

7.5 – 36

4 – 4.85

All parameters in spec. Digital and AOX output buffers still working, voltages

limited by VDD5 voltage. 5 V_REF, VVAR and VADCxREF are scaled down

to VDD5 voltage.

Low Batt, Low

VDD5

5.5 – 7.5

4 – 4.85

All parameters in spec. Current sources can be out of tolerance, but still

non-zero. Digital and AOX output buffers still working, voltages limited by

VDD5 voltage. 5V_REF, VVAR and VADCxREF are scaled down.

Resistance measurement is guaranteed for UBSW-V(IO)>1.5V that means if

UBSW = 5.5 V → IOx<4 V

Low Batt – 3V3

digital fault

3V3_FLT – 5.5

Configuration data is kept;

Input buffer is not able to reach 5 V full range;

VRS and SPI functionalities are in spec for UBSW down to 4.5 V.

SPI (frequency is not guaranteed) still run down to POR.

All analog functions are still on but parameters are out of tolerance.

VRS hysteresis features are not guaranteed in case UBSW is < 4.5 V.

3V3 digital fault

VPOR –

3V3_FLT

If 3V3_FLT = 1 all functions switched off. Only internal charge pump kept on

to guarantee no reset of internal logic

Low Batt

< VPOR

Device in OFF mode

1. The parameters depending on VDD5_REF are: ADC1 accuracy, pull-up voltage 5V and VVAR. They will have the same

tolerance in addition as VDD5_REF.
