Product Attributes

Features

• Small package size, wide force and measurement range, and high accuracy
• Force or measure voltages in the -2V to +7V through -7V to +13V ranges, dependent upon the supply voltage (VCC and VEE)
• Handle supply voltages of up to +30V (VCC to VEE) and a 20V device under test (DUT) voltage swing at full current
• Force or measure currents up to ±25mA with a lowest full - scale range of ±2μA
• Integrated support circuitry facilitates use of an external buffer amplifier for current ranges greater than ±25mA
• A voltage proportional to the measured output voltage or current is provided at the MSR_ output
• Integrated comparators, with externally set voltage thresholds, provide detection for both voltage and current levels
• The MSR_ and comparator outputs can be placed in a high - Z state
• Integrated voltage clamps limit the force output to levels set externally
• The force - current or the measure - current voltage can be offset - 0.2V to +4.4V (IOS)
• The MAX9949D/MAX9950D feature an integrated 10×Ω force - sense resistor between FORCE_ and SENSE_
• The MAX9949F/MAX9950F have no internal force - sense resistor
• Available in a 64 - pin 10mm X 10mm, 0.5mm pitch TQFP package with an exposed 8mm x 8mm die pad on the top (MAX9949) or the bottom (MAX9950) of the package for efficient heat removal
• The exposed paddle is internally connected to VEE
• Specified over the commercial 0°C to +70°C temperature range
• Five Programmable Current Ranges ±2μA, ±20μA, ±200μA, ±2mA, ±25mA
• -2V to +7V Through -7V to +13V Input Voltage Range and Higher (Up to 20V Voltage Swing at Full Current)
• Force - Current/Measure - Current Voltage Offset (IOS)
• Programmable Voltage Clamps for the Force Output
• Low - Leakage, High - Z Measure State
• 3 - Wire Serial Interface
• Low Power, 8mA (max) per PMU

Applications
