8-CHANNEL RELAY DRIVER
WITH INTEGRATED 5-V LDO AND ZERO-VOLT DETECTION
SLIS123D – JUNE 2006 – REVISED FEBRUARY 2008
The serial communications is an 8-bit format, with data transfer synchronized using a serial clock from the
microcontroller (see Figure 1). A single register controls all the outputs. The signal gives the instruction to control
the output of TPL9201.
The NCS signal enables the SCLK and MOSI data when it is low. After NCS is set low for T1, synchronization
clock and data begin to transmit and, after the 8-bit data has been transmitted, NCS is set high again to disable
SCLK and MOSI and transfer the serial data to the control register. SCLK must be held low when NCS is in the
high state.
