C-bus” updated: added EN,
PIDET and RESET pins
• Section 2 “Features and benefits”:
– added (new) first bullet item
– seventh bullet item changed from “and Fast-mode Plus at 1 MHz” to “and SMBus, Fast-mode
Plus up to 1 MHz”
• Section 2 “Features and benefits”, tenth bullet item:
– second sub-bullet changed from “3 V differential output (unloaded: ~5 V, loaded: ~1.5 V)”
to “1.5 V differential output with nominal terminals”
– sixth sub-bullet changed from “(1 M typical)” to “(200 k typical)”
• Figure 2 “Block diagram (level 0)” updated (added transistor on signal PIDET)
• Figure 3 “Differential output driver simplified circuit” updated (corrected transistor types)
• Table 3 “Pin description”:
– updated description for V
DD(A)
(pin 1)
– updated description for EN (pin 3)
– description for VDDA_SEL (pin 9) changed from “Floating is not information of V
DD(A)
range.
Recommend to be HIGH when V
DD(A)
> 2.3 V and be LOW when V
DD(A)
< 2.3 V through a
resistor.” to “Floating automatically selects threshold based on V
DD(A)
magnitude. Recommend to
be HIGH when V
DD(A)
> 2.2 V and be LOW when V
DD(A)
< 2.4 V through a resistor.”
• Figure 5 “dI
