PRINCIPLES OF OPERATION
serial data operation
The TPIC46L01, TPIC46L02, and TPIC46L03 offer serial input interfaces to the microcontroller to transfer
control data to the predriver and output fault data back to the controller. The serial input interface consists of:
D SCLK − Serial clock
D CS − Chip select
D SDI − Serial data input
D SDO − Serial data outpu
Serial data is shifted into the least significant bit (LSB) of the SDI shift register on the rising edge of the first SCLK
after CS has transitioned from 1 to 0. Eight clock cycles are required to shift the first bit from the LSB to the most
significant bit (MSB) of the shift register. Less than eight clock cycles result in fault data being latched into the
output control buffer. The first two bits are unused and the last six bits are the output control data. A low-to-high
transition on CS latches the contents of the serial shift register into the output control register. A 0 input to SDI
turns the corresponding parallel output off and a 1 turns the output on (see Figure 12).
