8.3 Recommended Operating Conditions

MIN NOM MAX UNIT
VDD Supply pin voltage 1.7 5.5 V
VSENSE Input pin voltage 0 5.5 V
VCT CT pin voltage (1)(3) VDD V
VRESET Output pin voltage 0 5.5 V
VMR MR pin Voltage (2) 0 5.5 V
IRESET Output pin current 0.3 10 mA
TJ Junction temperature (free-air temperature) -40 125 ℃
(1) CT pin connected to VDD pin requires a pullup resistor;  10 kΩ is recommended.
(2) If the logic signal driving MR is less than VDD, then additional current flows into VDD and out of MR.
(3) The maximum rating is VDD or 5.5 V, whichever is smaller.
