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 8 µF in series with 0.3.

SG – Signal Ground  
The Signal Ground provides a Kelvin return for the PC and TM  
ports. It is internally connected to the –IN port. The SG  
connection is not sized to carry the –IN current and cannot be a  
substitute for the –IN port, which must be connected with low  
interconnect impedance.

PC – Primary Control  
The Primary Control port is a multifunction node that provides  
the following functions:  
+Out  
–Out  
Enable/Disable – If the PC port is left floating or is at a  
logic HI, the BCM output is enabled. Once this port  
is pulled lower than 2.4 Vdc with respect to SG, the output  
is disabled. This action can be realized by employing a  
relay, opto-coupler, or open collector transistor. Refer to  
Figures 1-3, 13 and 14 for the typical Enable/Disable  
characteristics. This port should not be toggled at a rate  
higher than 1 Hz.  
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 +/-5 °C. SG should be used as ground  
return of the TM signal to maintain the specified accuracy.  
+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 28. 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.  
Alarm – The BCM contains watchdog 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 14 for  
PC alarm characteristics.  
The low output impedance of the BCM, see Figure 9, reduces  
or eliminates the need for limited life aluminum electrolytic or  
tantalum capacitors at the input of POL converters.  
TM – Temperature Monitor  
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 (see Figure 9), low  
frequency bypass capacitance and significant energy storage  
may be more densely and efficiently provided by adding  
capacitance at the input of the BCM.  
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.
