°C, unless otherwise specified)

Note :

1. Power Supply ON Delay (PSON :High

→ Low). Power Supply is Active when PSON is Low.

2. Power Supply OFF Delay (PSON :Low

→ High). Power Supply is Off when PSON is High.

3. Ton = (Cpin8 * Von) / lon = (Cpin8 * VthH) / lon

4. Toff = (Cpin8 * Voff) / loff = [Cpin8 * (V8max - VthL)] / (VRd / Rd)

5,6,7,8 : These parameters, although guaranteed, are but not 100% tested in production.
