Description
DUT Voltage Sense Input (High Sense) for Channel 3.
DUT Voltage Sense Input (High Sense) for Channel 1.
Guard Output Drive for Channel 1.
Sense Input (Low Sense) for High Current Range (Channel 1).
Sense Input (High Sense) for High Current Range (Channel 1).
Compensation Capacitor Input for Channel 1. See the Compensation Capacitors section.
External Force Signal Input. This pin enables the connection of the system PMU.
External Sense Signal Output. This pin enables the connection of the system PMU.
Accurate Analog Reference Input Ground.
Reference Input for DAC Channels (5 V for specified performance).
Interface Select Pin. Logic low selects SPI-compatible interface mode; logic high selects LVDS interface mode.
Guard Amplifier Input for Channel 1/DUTGND Input for Channel 1. This dual function pin is configured via the
serial interface. The default function at power-on is GUARDIN1. If this pin is configured as a DUTGND input for
the channel, the input to the guard amplifier is internally connected to MEASVH1. For more information, see
the Device Under Test Ground (DUTGND) section and the Guard Amplifier section.
Force Output for Internal Current Ranges (Channel 1).
External Capacitor for Channel 1. This pin optimizes the stability and settling time performance of the force
amplifier when in force voltage mode. See the Compensation Capacitors section.
Force Output for High Current Range (Channel 1). Use an external resistor at this pin for current ranges up to
±80 mA. For more information, see the Current Range Selection section.
Multiplexed DUT Voltage, Current Sense Output, Temperature Sensor Voltage for Channel 3. This pin is
referenced to AGND.
Multiplexed DUT Voltage, Current Sense Output, Temperature Sensor Voltage for Channel 2. This pin is
referenced to AGND.
Multiplexed DUT Voltage, Current Sense Output, Temperature Sensor Voltage for Channel 1. This pin is
referenced to AGND.
Multiplexed DUT Voltage, Current Sense Output, Temperature Sensor Voltage for Channel 0. This pin is
referenced to AGND.
DUT Voltage Sense Input (Low Sense). By default, this input is shared among all four PMU channels. If a DUTGND
input is required for each channel, the user can configure the GUARDINx/DUTGNDx pins as DUTGND inputs for
each PMU channel.
This pin has a pull-down current source (~350 μA). In LVDS interface mode, the CPOHx and CPOLx pins default
to differential interface pins.
Open-Drain Output for Guard and Clamp Alarms. This open-drain pin provides shared alarm information
about the guard amplifier and clamp circuitry. By default, this output pin is disabled. The system control
register allows the user to enable this function and to set the open-drain output as a latched output. The user
can also choose to enable alarms for the guard amplifier, the clamp circuitry, or both. When this pin flags an
alarm, the origins of the alarm can be determined by reading back the alarm status register. Two flags per
channel in this word (one latched, one unlatched) indicate which function caused the alarm and whether the
alarm is still present.
Open-Drain Output for Temperature Alarm. This latched, active low, open-drain output flags a temperature
alarm to indicate that the junction temperature has exceeded the default temperature setting (130°C) or the
user programmed temperature setting. Two flags in the alarm status register (one latched, one unlatched)
indicate whether the temperature has dropped below 130°C or remains above 130°C. User action is required
to clear this latched alarm flag by writing to the clear bit (Bit 6) in any of the PMU registers.
Digital Reset Input. This active low, level sensitive input resets all internal nodes on the device to their power-
on reset values.
Force Output for High Current Range (Channel 0). Use an external resistor at this pin for current ranges up to
±80 mA. For more information, see the Current Range Selection section.
