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 Programmable Current and Voltage Compliance
o Programmable Current Ranges

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.

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
