or
Under-Voltage Lockout (UVLO)
The IC turns off all MOSFETs and remains in a low
quiescent current state until VIN rises above the UVLO
threshold.
I2C Interface
The FAN5365’s serial interface is compatible with standard,
fast, fast plus, and high-speed mode I
2C bus specifications.
The FAN5365’s SCL line is an input and its SDA line is a bi-
directional open-drain output; it can only pull down the bus
when active. The SDA line only pulls LOW during data reads
and when signaling ACK. All data is shifted in MSB (bit 7) first.
Slave Address
In Table 6, A1 and A0 are according to the Ordering
Information table on page 2.

In Hex notation, the slave address assumes a 0 LSB. For
example, the hex slave address of option 00 is 94H.
Register Addressing
FAN5365 has four user-accessible registers:

Bus Timing
As shown in Figure 39, data is normally transferred when
SCL is LOW. Data is clocked in on the rising edge of SCL.
Typically, data transitions shortly at or after the falling edge
of SCL to allow ample time for the data to set up before the
next SCL rising edge.

Figure 39. Data Transfer Timing
Each bus transaction begins and ends with SDA and SCL
HIGH. A transaction begins with a “START” condition, which
is defined as SDA transitioning from 1 to 0 with SCL HIGH,
as shown in Figure 40.

A transaction ends with a “STOP” condition, which is defined
as SDA transitioning from 0 to 1 with SCL HIGH, shown in

Figure 41. Stop Bit
During a read from the FAN5365 (Figure 44), the master
issues a “Repeated Start” command after sending the
register address and before resending the slave address.
The “Repeated Start” is a 1-to-0 transition on SDA while SCL
is HIGH, as shown in Figure 42.
