17 / 45 page  3.2.1.8.2.2 Open drain (DIS) All parameters are tested and guaranteed in the following conditions, unless otherwise specified: 4.5 V ≤ VVDD ≤ 5.5 V ; -40 °C < Tj < 125 °C Table 13. Open drain electrical characteristics Symbol Parameters Test conditions Min Typ Max Unit VDISL - DIS output level when the pull down stage is ON IDIS = 5 mA - - 0.4 V IDIS_LIM - DIS output current limitation for VDIS = 5 V 8 - 18 mA TDIS_PULLDOWN Time interval after POR_MAIN when DIS pin is internally pulled-down, upon a wake up by VIF. Purpose is to trigger interrupt in the MCU or wake up on a PMIC. Guaranteed by SCAN - 800 - ms TDIS_DEGLITCH Up/Reset counter to avoid positive glitches on DIS input when the L9963T is in Normal state. The counter counts up if DIS = 1, while it is reset if DIS = 0. Guaranteed by SCAN 1 2 3 μs 3.2.2 Analog input 3.2.2.1 SPICLKFREQ SPICLKFREQ pin is an analog input, compared to four thresholds by a set of analog comparators. An external resistor RCLKPD must be connected between SPICLKFREQ and GND, in order to generate a voltage VSPICLKFREQ = RCLKPD * ISPICLKFREQPU. The code obtained from these 4 comparators outputs (as indicated in the following table) is latched in the Trimming & Config Latch to determine the SPI Clock frequency when L9963T works in Master mode (NSLAVE = 1).
