4.1
The SPIDER - TLE7232G is an eight channel low-side relay switch. The power stages
are built by N-channel vertical power MOSFET transistors.
4.1.1
The SPIDER - TLE7232G is supplied by power supply line
digital as well as the analog functions of the device including the gate control of the
power stages. There is a power-on reset function implemented for the supply line. After
start-up of the power supply, all SPI registers are reset to their default values. A capacitor
at pins VDD to GND is recommended.
The voltage at pin VSO is used by the driver of the SO line at the SPI. It is designed to
be functional at a wide voltage range.
There is a reset pin available. At low level at this pin, all registers are set to their default
values and the quiescent supply current is minimized.
4.1.2
There is an input pin available at SPIDER - TLE7232G to control the output stages.
