(1)

RLRESET and CLRESET are the resistor and capacitor connected to the RESET pin.

(2)

The lowest supply voltage (VDD) at which RESET becomes active. Trise(VDD) ≥ 15 μs/V.

7.5 Electrical Characteristics

1.7 V

≤ VDD ≤ 6.5 V, RLRESET = 100 kΩ, CLRESET = 50 pF, over operating temperature range (TJ = –40°C to 125°C), unless

otherwise noted. Typical values are at TJ = 25°C
