TLE75602-ESD

SPIDER+ 12V

Power Supply

Table 7 shows the correlation between device operation modes, VS and VDD supply voltages, and state of the

most important functions (channels operativity, SPI communication and SPI registers).

6.1.1

Power-up

The Power-up condition is satisfied when one of the supply voltages (VS or VDD) is applied to the device and the

INn or IDLE pins are set to “high”. If VS is above the threshold VS(OP) or if VDD is above the threshold VDD(LOP) the

internal power-on signal is set.

6.1.2

Sleep mode

When TLE75602-ESD is in Sleep mode, all outputs are OFF and the SPI registers are reset, independently from

the supply voltages. The current consumption is minimum. See parameters IVDD(SLEEP) and IVS(SLEEP), or

parameter ISLEEP for the whole device.

6.1.3

Idle mode

In Idle mode, the current consumption of the device can reach the limits given by parameters IVDD(IDLE) and

IVS(IDLE), or by parameter IIDLE for the whole device. The internal voltage regulator is working. Diagnosis

functions are not available. The output channels are switched OFF, independently from the supply voltages.

When VDD is available, the SPI registers are working and SPI communication is possible. In Idle mode the ERRn

bits are not cleared for functional safety reasons.
