These values will not change over normal oper- ating and storage conditions. However, in applications where the standard thresholds are not exactly right, or if higher precision is needed in the threshold value, the X46402 trip points may be adjusted. The procedure is described below, and uses the application of a high volt- age control signal. Setting the VTRIP Voltage This procedure is used to set the VTRIP,V2TRIP to a higher voltage value. For example, if the current VTRIP is 4.4V and the new VTRIP is 4.6V, this procedure will directly make the change. If the new setting is to be lower than the current setting, then it is necessary to reset the trip point before setting the new value. To set the new voltages, apply the desired VTRIP thresh- old voltage to the Vcc pin, the V2TRIP voltage to the V2MON pin, then tie the RESET pin to the programming voltage VP. Then, write data 01h or 0Dh address 00h to program VTRIP, V2TRIP respectively. The stop bit following a valid write operation initiates the programming sequence. Bring RESET LOW to complete the operation. Note: this operation also writes 01h, or 0Dh to address 00h. Resetting the VTRIP Voltage This procedure is used to set the VTRIP, the V2TRIP to a “native” voltage level. For example, if the current VTRIP is 4.4V and the new VTRIP must be 4.0V, then the VTRIP must be reset. When the threshold is reset, the new level is something less than 1.7V. This procedure must be used to set the voltage to a lower value. To reset the new VTRIP, V2TRIP voltage, apply the desired VTRIP or V2TRIP threshold voltage to the Vcc or V2MON pin, respectively, and tie the RESET pin to the program- ming voltage VP. Then write 03h or 0Fh to address 00h. The stop bit of a valid write operation initiates the pro- gramming sequence. Bring RESET LOW to complete the operation. Note: this operation also writes 03h or 0Fh to address 00h of the EEPROM array. Figure 6. Sample VTRIP Reset Circuit 5 4 7 1 8 2 6 3 X46402 VTRIP Adj.
