25V Span, 800mA Device Power Supply (DPS)  
MAX59  
General Description  
Features  
The MAX9959 provides all the key features of a device  
power supply (DPS) common to automatic test equip-  
ment (ATE) and other instrumentation. Its small size,  
high level of integration, and superb flexibility make the  
MAX9959 ideal and economical for multisite systems  
requiring many device power supplies.  
o 25V Span Output Voltage  
o Programmable Current and Voltage Compliance  
o Programmable Current Ranges  
2ꢀꢀµA  
2mA  
The MAX9959 has multiple input control voltages that  
allow independent setting of both the output voltage,  
and the maximum and minimum (smallest positive or  
most negative) voltage or current. The MAX9959 is a  
voltage source when the load current is between the  
two programmed limits, and transitions gracefully into a  
precision current source/sink if a programmed current  
limit is reached. The output features two independently  
adjustable voltage clamps that limit both the negative  
and positive output voltage values between levels  
externally provided.  
2ꢀmA  
8ꢀꢀmA  
o Load Regulation of 1mV at 8ꢀꢀmA  
o External Buffer Support for Higher Currents  
o Parallel Multiple Devices for Higher Currents  
o Programmable Gain Allows a Wide Range of DACs  
o Device-Under-Test (DUT) Ground Sense  
o Programmable Compensation for Wide Range  
The MAX9959 can source voltages spanning 25V and  
can source currents as high as ±±88mA. The DPS can  
support an external buffer for sourcing and sinking  
higher currents. Multiple MAX9959s can be configured  
in parallel to load-share, allowing higher output currents  
with greater flexibility.  
of Loads  
o Integrated Go/No-Go Comparators  
o IDDQ Test Mode  
o Range-Change Glitch Control  
o Compact (14mm x 14mm) Package  
o 3-Wire Compatible Serial Interface  
o Thermal Warning Flag and Thermal Shutdown  
The MAX9959 features operation over a wide range of  
loading conditions. Programmability allows optimizing  
of settling time, over-/undershoot, and stability. Built-in,  
configurable, range-change glitch-control circuits mini-  
mize output glitches during range transitions.  
The MAX9959 offers load regulation of 1mV at ±88mA  
load.  
The MAX9959D features an internal 388kΩ sense  
resistor (R ), between RCOMF and SENSE. The  
FS  
Ordering Information  
MAX9959F does not include this sense resistor. Both  
devices are available in the 188-pin TQFP package with  
an exposed pad on the top for heat removal.
