Edge4717D Quad Channel, Per Pin Precision Measurement Unit TEST AND MEASUREMENT PRODUCTS Description The Edge4717D is a precision measurement unit designed for automated 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 Edge4717D Features a PMU that can force or measure voltage over a typical 15V I/O range, and supports 4 current ranges: ± 3.2 µA, ± 80 µA, ± 2 m A, ± 30 m A. The Edge4717D has an on-board window parator per channel that provides two bits of information - DUT too high and DUT too low. There is also a monitor pin which provides a real time analog signal proportional to either the voltage or current measured at the DUT. The Edge4717D is designed to be a low power, low cost, small footprint solution to allow high pin count testers to support a PMU per pin. On-board voltage clamps, with over-current detection, provide protection to the DUT and 4717D. The Edge4717D also has a sample-and-hold feature available for capturing DUT current or voltage measurements. The Edge4717D is a design improvement to the Edge4717 that Features : - Increased FV/MV range - Improved over-current detection circuit functionality - LVTTL parator outputs (pull-up resistors no longer required) - Improved Hi Z switching characteristics - Improved Force Voltage Linearity Features - - - - - - - - - - FV / MI Capability FI / MV Capability FV / MV Capability FI / MI Capability 4 Current Ranges (± 3.2 µA, ± 80 µA, ± 2 m A, ± 30 m A) - 5.5V to 9.5V Nominal Output Range (Zero Current) - 3.5 to 7.5V Nominal Output Range (Full Scale Current) On-board Voltage Clamps Internal Sample and Hold 228 Pin 23 mm x 23 mm TBGA Package Functional Block Diagram CHANNEL 0 SNK_MON SRC_MON Hi Z VINP REF FV / FI- MI / MV- IVMAX IVMIN P_IN DISABLE PARATORS DETECTOR LOGIC VOLTAGE MONITOR DUT_GND OVER-CURRENT DETECT OVER-CURRENT DETECT SNK_OUT OPEN_RLY SRC_OUT FORCE GUARD SENSE DUTLTH DUTGTL...
