4 Device Comparison

Figure 4-1 and Figure 4-3 shows the device nomenclature of the TPS3423 and TPS3424, for output / push-

button input, short press and long press, interrupt, reset and kill timing options.Figure 4-2 extends nomenclature

of TPS3423 to provide 2 different timing option for channels. Refer Section 7 for more details. Contact TI sales
