Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C/S OUT | output | Output of the internal current-sense amplifier, which has a fixed gain of 20 and may be bypassed to ground with an external capacitor to limit bandwidth. |
| 2 | C/S (+) | input | Non-inverting input of the differential current-sense amplifier, used across an external shunt in the power-return line, with a common-mode range up to VCC-2 V. |
| 3 | C/S (-) | input | Inverting input of the differential current-sense amplifier, used with C/S (+) across the shunt to set a sense voltage between 50 mV and 500 mV. |
| 4 | (-) SENSE | input | High-impedance remote sense input for the system ground, regarded as the true ground to which all voltages are referenced. |
| 5 | POWER RTN | power_in | Most negative voltage in the system, which can range from 0 V to 5 V below (-) SENSE and should be connected as close to the power source as possible. |
| 6 | ARTIFICIAL GND | power_out | Low-impedance internal circuit ground held exactly 250 mV above (-) SENSE to provide headroom for the ground buffer amplifier. |
| 7 | VREF | power_out | Internal band-gap voltage reference set at 2.0 V with respect to (-) SENSE (1.75 V above artificial ground) with ±1.5% accuracy. |
| 8 | ISET | output | Current-setting output of the drive amplifier, which is normally configured with a resistor to ground and has a fixed voltage gain of 2.5. |
| 9 | OPTO DRIVE | output | Current-sinking drive output for an optocoupler, which can be biased from 4.5 V to 35 V and sinks up to 20 mA. |
| 10 | VCC | power_in | Supply input rated 4.5 V to 35 V, with undervoltage lockout that disables internal bias until the reference is in regulation. |
| 11 | (+) SENSE | input | High-impedance sense input of the voltage feedback amplifier, where the reference is measured and trimmed to 2 V ±1.25%. |
| 12 | COMP | passive | Voltage-amplifier output and compensation node, which swings from slightly above the ground return up to an internal 2.0 V clamp, where overall loop compensation is normally applied. |
| 13 | ADJ INPUT | input | Input of the transconductance adjust amplifier, which compares the module output current against the share bus and carries a built-in 50 mV offset on its inverting input. |
| 14 | ADJ OUT | output | Output of the adjust amplifier, which can adjust the reference by up to 100 mV and is typically filtered with a capacitor to ground. |
| 15 | CURRENT SHARE BUS | bidirectional | Current-share bus driven by a unidirectional low-impedance buffer that only sources current, protected against shorts to ground and accidental voltages up to 50 V. |
| 16 | STATUS INDICATE | output | Open-collector output that is pulled low to flag the master unit, with a sink current rating of 20 mA and a VOUT low of 0.5 V maximum. |
