The V•I Chip input voltage range should not be exceeded. An  
internal under/over voltage lockout-function prevents operation  
outside of the normal operating input range. The BCM turns  
ON within an input voltage window bounded by the “Input  
under-voltage turn-on” and “Input over-voltage turn-off” levels,  
as specified. The V•I Chip may be protected against accidental  
application of a reverse input voltage by the addition of a  
rectifier in series with the positive input, or a reverse rectifier in  
shunt with the positive input located on the load side of the  
input fuse.

The connection of the V•I Chip to its power source should be  
implemented with minimal distribution inductance. If the  
interconnect inductance exceeds 100 nH, the input should be  
bypassed with a RC damper to retain low source impedance and  
stable operation. With an interconnect inductance of 200 nH, the  
RC damper may be 10 µF in series with 0.3. A single  
electrolytic or equivalent low-Q capacitor may be used in place  
of the series RC bypass.

PC – Primary Control  
The Primary Control port is a multifunction node that provides  
the following functions:

Enable/Disable – If the PC port is left floating, the BCM  
output is enabled. Once this port is pulled lower than  
2.4 Vdc with respect to –IN, the output is disabled. This  
action can be realized by employing a relay, opto-coupler,  
or open collector transistor. Refer to Figures 1-3, 12 and 13  
for the typical Enable/Disable characteristics. This port  
should not be toggled at a rate higher than 1 Hz. The PC  
port should also not be driven by or pulled up to an external  
voltage source.

+OUT/-OUT – DC Voltage Output Ports  
Two sets of contacts are provided for the +OUT port. They  
must be connected in parallel with low interconnect resistance.  
Similarly, two sets of contacts are provided for the –OUT port.  
They must be connected in parallel with low interconnect  
resistance. Within the specified operating range, the average  
output voltage is defined by the Level 1 DC behavioral model  
of Figure 26. The current source capability of the BCM is rated  
in the specifications section of this document.  
Primary Auxiliary Supply – The PC port can source up to  
2.4 mA at 5.0 Vdc. The PC port should never be used to  
sink current.  
Alarm – The BCM contains circuitry that monitors output  
overload, input over voltage or under voltage, and internal  
junction temperatures. In response to an abnormal  
condition in any of the monitored parameters, the PC port  
will toggle. Refer to Figure 13 for PC alarm characteristics.  
The low output impedance of the BCM, reduces or eliminates  
the need for limited life aluminum electrolytic or tantalum  
capacitors at the input of POL converters.  
TM – Temperature Monitor  
The Temperature Monitor port monitors the highest junction  
temperature of the BCM. This output may be used to provide  
feedback and validation of the thermal management of  
V•I Chips, as applied in diverse power systems and environments.  
Total load capacitance at the output of the BCM should not  
exceed the specified maximum. Owing to the wide bandwidth  
and low output impedance of the BCM, low frequency bypass  
capacitance and significant energy storage may be more  
densely and efficiently provided by adding capacitance at the  
input of the BCM.  
At 300°K (+27°C), the TM output is nominally 3.0 Vdc. The  
TM output is proportional to temperature and varies at 10 mV/°C.  
The TM accuracy is typically +/-5°C. A kelvin connection to  
the –IN port of the BCM should be used as the ground return of  
the TM signal to maintain the specified accuracy.
