Application Notes (continued)
[7] Parallel synchronous operation of multiple ICs
Multiple instances of this IC can be operated in parallel. All the ICs will operate at the same frequency if the master
and slave IC OSC pins (pin 9) are connected directly.
1. Notes on S.C.P. operation during parallel operation
In the circuit in figure 6, if either the IC operating in master mode or the IC in slave mode detects a short circuit,
the IC that detected the short circuit will enter latched mode. The latched mode state is a state in which the
output is shut off and both the RB pin and the SS pin are set to the low level. However in this mode, this IC has
an added function that holds the OSC pin at the high level (about 0.8 V).
When OSC pin of the IC that did not enter latched mode goes to the high level, the internally fixed dead- time
voltage (about 0.6 V) will then be lower than the OSC pin voltage, and internal PWM circuit output will stop.
That will cause this IC to go to the output shorted state, and then, this IC will also switch to latched mode.
Therefore, applications that require parallel synchronous operation should adopt the basic circuit structure
shown in figure 6.
2. Usage notes
1)
If capacitors are shared as shown in figure 7 to reduce the number of external components:
The charge current will be doubled.
The short-circuit protection circuit will not operate if the S.C.P. pin capacitor is shared.
In this circuit, even if the master IC detects a short circuit, the slave IC will not detect that state, so the
S.C.P. pin will remain fixed at the low level state. Note that as a result, the short-circuit protection circuit
will not operate and the IC will continue to operate at the maximum duty drive.
2)
Note that it is not possible to operate this IC (the AN8016NSH) with the two-channel AN8017SA/AN8018SA
together in parallel synchronous mode.
