SLVSDF3F MARCH 2017 – JANUARY 2019 TPSM846C23
The TPSM846C23 device provides flexible user adjustment of the undervoltage lockout (UVLO) threshold and hysteresis. The minimum VIN voltage required for power conversion is set by the stored VIN_ON (35h) value. The factory default value is 4.5 V. The turnon value can be set from 4.25 V to 7.75 V in 250-mV steps. The turnoff threshold voltage is stored in the VIN_OFF (36h) value. The factory default is 4 V. The value can be set from 4 V to 7.5 V in 250-mV steps. For more information, see Table 2.
