The TLE7233G is supplied by two power supply lines
to be functional at a very wide voltage range. The analog power supply
Power-on reset functions have been implemented for both supply lines. After start-up of the power supply, all SPI
registers are reset to their default values and the device remains in idle mode. Capacitors at pins
V
A reset pin is available. At low logic level at this pin, all registers are set to their default values and the quiescent
supply currents are minimized.

To enable the Daisy chain functionality it is necessary to have
The device provides a sleep mode to minimize current consumption, which also resets the register banks. It is
controlled by a low active reset pin (RST) which disables the device and minimize the current consumption. The
table below gives an overview of the different power modes.
