THERMAL SHUTDOWN
TTRIP Thermal shutdown trip point 140 °C
(1) During short circuit condition driver current limit comparator will trip and short is detected and driver goes into STANDBY and short flag is set high in the status register.
(2) When testing VCM open or short this is the recommended minimum VCM code (in dec) to be used.
(3) This is the voltage that is needed for the feedback resistor and high side driver. It should be noted that the maximum VCM resistance is limited by this voltage and supply voltage. For example, 3-V supply maximum VCM resistance is: RVCM = (VBAT – VDRP)/IVCM = (3 V - 0.4 V)/102.3 mA = 25.4 Ω.
(4) During shutdown to standby transition VIH low limit is 1.28 V.
(5) During shutdown to standby transition VIL high limit is 0.51 V.
