SPI timing

All SPI timing is performed with a 150 pF load on MISO unless otherwise noted

4.9V

 VDD  5.1V; 7V  VRESX  37V; 7V  VSDIAG  37V; (VSATS + 6V)  VSYNC  25V; 5V

 VSATS  14V; FEN1 = FEN2 = FEN3 = FEN4 = VDD; R_REF = 10K, ±1%, 100PPM; -

40°C

 TA  +95°C; unless other specified.

tCLKN

Time between CS rising edge and first transition

of SCLK must be higher than tCLKN. It happens

when multiple L9662 are connected to the same

SCLK and MOSI but with different chip select.

1. Parameters tDIS and tHO shall be measured with no additional capacitive load beyond the normal test fixture capacitance

on the MISO pin. Additional capacitance during the disable time test erroneously extends the measured output disable

time, and minimum capacitance on MISO is the worst case for output hold time.
