MAX4810/MAX4811/MAX4812
The MAX4810/MAX4811/MAX4812 integrated circuits
generate high-voltage, high-frequency, unipolar or bipo-
lar pulses from low-voltage logic inputs. These dual
pulsers feature independent logic inputs, independent
high-voltage pulser outputs with active clamps and
independent high-voltage supply inputs.
The MAX4810/MAX4811/MAX4812 feature a 9Ω output
impedance for the high-voltage outputs, and a 27Ω
impedance for the active clamp. The high-voltage out-
puts are guaranteed to provide 1.3A output current.
All devices use three logic inputs per channel to control
the positive and negative pulses and active clamp. Also
included are two independent enable inputs. Disabling
EN ensures the output MOSFETs are not accidentally
turned on during fast power-supply ramping. This allows
for faster ramp times and smaller delays between puls-
ing modes. A low-power shutdown mode reduces
power consumption to less than 1µA. All digital inputs
are CMOS compatible.
The MAX4810 includes clamp output overvoltage pro-
tection, while the MAX4811 features both pulser output
and clamp output overvoltage protection. The MAX4812
does not provide overvoltage protection. See the
Ordering Information/Selector Guide.
The MAX4810/MAX4811/MAX4812 are available in a
56-pin (7mm x 7mm), TQFN exposed-pad package and
are specified over the 0°C to +70°C commercial tem-
perature range.

Note 1:
This specification is based on the thermal characteristic of the package, the maximum junction temperature, and the setup
described by JEDEC 51. The maximum power dissipation for the MAX4810/MAX4811/MAX4812 might be limited by the thermal
protection included in the device.
Note 2:
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations, refer to
www.maxim-ic.com/thermal-tutorial.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
