Notes:

1. Represent typical values at 25°C, V1MON = 12 V, and V2MON = 12 V.

2. Does not apply if V2MON is a digital signal.

3. The RESET short-circuit current is the maximum pullup current when RESET is driven low by a μP bidirectional reset pin.

4. It is typical for the SCL and SDA have resistors to be pulled up to V3MON. However, care must be taken to ensure that the minimum VIH is met when the SCL and SDA are driven directly from a low voltage

logic controller without pull-up resistors.

5. Initial V2MON ON minimum remains as 2.2V but the -0.3V to 30V specifications apply afterwards.

6. VOTP can be furnished by Factory 6V power supply, rather than on-board power supply, when performing factory programming. A 10uF tantalum capacitor is required on VOTP during operation regardless

of whether the OTP fuses are programmed.

7. The OTP settling time occurs only once if OTP function is used.

8. Guaranteed by design and not subject to production test.
