SNVSCK5A April 2024 – August 2024 TPS3842
PRODUCTION DATA
TPS3842 device offers built-in hysteresis around the UV threshold to avoid erroneous RESET deassert. The hysteresis (VHYS) is opposite to the threshold voltage for undervoltage options hysteresis is added to the negative threshold (VITN).
Part Number | DEVICE HYSTERESIS OPTION |
---|---|
TPS3842Axx1DRLR | 1% |
TPS3842Axx5DRLR | 5% |
TPS3842Axx0DRLR | 10% |
Knowing the amount of hysteresis voltage, the release voltage for the undervoltage (UV) channel is (VITN + VHYS). Hysteresis is dependent on the device VITN including VITN accuracy and deviations.
Undervoltage (UV)
VITN = 700mV
Voltage Hysteresis (VHYS) = 1% = VITN x 1% = 7mV
Release Voltage = VITN + VHYS = 707mV
