Electrical Characteristics (Cont.)

Notes:

(1) Guaranteed by design.

(2) See 5V Detect Thresholds below.

(3) Recommended source impedance for 5V supply: £ 0.25W (0.2W for SC1531A). This will ensure that

IO x RSOURCE < VHYST, thus avoiding DR toggling during 5V detect threshold transitions.

(4) In Application Circuit on page 1.

(5) See Timing Diagram below.

5V Detect Thresholds(1)

Note:

(1) VIN rise and fall times (10% to 90%) to be ³ 100µs.
