Power Supply
5 Power Supply
The TLE7233G is supplied by two power supply lines VDD and VDDA. The digital power supply line VDD is designed
to be functional at a very wide voltage range. The analog power supply VDDA supports 5 V 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 VDD - GND and
VDDA - GND are recommended.
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.
The VDD supply line is used for the I/O buffer circuits of the SPI pins, therefore the voltage on the SO pin is always
related to this supply voltage. A capacitor between pins VDD and GND is recommended (especially in case of EMI).
To enable the Daisy chain functionality it is necessary to have VDD and VDDA in the specified functional range.
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.
