DS2109
NOTES:
1. PDI, PDE, TCS
2. 4.00V < TERMPWR < 5.25V.
3. 0.0V < signal lines < 3.0V.
4. All signal lines = 0.0V.
5. All signal lines open.
6. Power down enabled.
7. Guaranteed by design; not production tested.
8. C14 slightly higher capacitance due to sensing circuitry.
9. Excluding PDI, PDE pins.
10. PDO output pin.
11. IBCST > 32 mA – disable termination.
12. Excluding PDE, PDI, R14, and TCS pins.
28–PIN SOIC (300 MIL)
The chamfer on the body is optional. If it is not present, a termi-
nal 1 identifier must be positioned so that 1/2 or more of its area
is contained in the hatched zone.
