SNVSCN9 September 2024 TPS3423 , TPS3424
ADVANCE INFORMATION
TPS3424x11xxx8DRLR has options to program short press duration (tSP) and long press duration (tLP) with capacitor on SPT pin and LPT pin respectively. Equation 1 shows the relation between the press duration and the capacitance. If the pin is left floating, the device defaults to fixed timer of 50msec. Connecting a capacitor which provides less than 50msec press duration as per, programs to 50msec press duration. Make sure tLP is greater than tSP for proper device operation.
