Description
Edge4707B
Quad Channel Per-Pin
Precision Measurement Unit
Features
The Edge4707B is a precision measurement unit designed
for automatic test equipment and instrumentation.
Manufactured in a wide voltage CMOS process, it is a
monolithic solution for a quad channel per pin PMU.
Each channel of the Edge4707B features a PMU that can
force or measure voltage over a 15V I/O range, and
supports 4 current ranges: 2 µA, 200 µA, 20 µA, and 2
mA.
Each channel of the Edge4707B features an on-board
window comparator that provides two bits of information:
DUT too high and DUT too low. There is also a monitor
function which provides a real time analog signal
proportional to either the measured voltage or current.
The Edge4707B is designed to be a low power, low cost,
small footprint solution to allow high pin count testers to
support a PMU per pin.
In addition, two independent switches per channel (for a
central PMU force and sense) plus two wide voltage analog
muxes per channel are included.

Circuit Description (continued)
Short Circuit Protection
The Edge 4707B is designed to survive a direct short circuit
to any legal voltage at the FORCE and SENSE pins, by
virtue of a limited current, which results from the presence
of an external current sense resistor (normally 1 KΩ to
1MΩ) in the FORCE path.
Transient Clamps
The Edge 4707B has on-board clamps to limit the voltage
and current spikes that might result from either changing
the current range or changing the operating mode.
Power Supply Sequencing
In order to avoid the possibility of latch-up, the following
power-up requirements must be satisified:
1. VEE ≤ GND ≤ VDD ≤ VCC at all times
2. VEE ≤ All inputs ≤ VCC
The following power supply sequencing can be used as a
guideline when operating the Edge4707:
Power Up Sequence
1. VCC (substrate)
2. VEE/VDD
3. Digital Inputs
4. Analog Inputs
Power Down Sequence
1. Analog Inputs
2. Digital Inputs
3. VEE/VDD
4. VCC (substrate)
