ISL70061SEH, ISL73061SEH
Radiation Hardened 10A PMOS Load Switch
The ISL70061SEH and ISL73061SEH
(ISL7x061SEH) are radiation hardened single
Features
• Electrically screened to DLA SMD 5962-19208
• Integrated high speed load switch
○ Turn-off time of 3µs
channel load switches featuring ultra-low r and
ON
controlled rise time. These devices use a PMOS pass
device as the main switch that operates across an
input voltage range of 3V to 5.5V and can support a
maximum of 10A continuous current. Simple ON/OFF
digital control inputs make the device capable of
interfacing directly with low voltage control signals
from an FPGA, MCU, or processor.
• Ultra-low ON-resistance (r ) of 14mΩ typical
ON
• Continuous 10A switch current
• Controlled rise time to minimize inrush current
• Reverse current protection
Additional features include reverse current protection
to stop current from flowing toward the input when the
output SWO voltage increases above the input SWI
voltage, a selectable 122Ω MOSFET to discharge the
output, and Undervoltage Lockout (UVLO) protection
that keeps the switch OFF when the input voltage is
too low.
• Simple ON/OFF logic control
• Undervoltage lockout
• Selectable 122Ω discharge MOSFET
• Radiation acceptance testing - ISL70061SEH
○ HDR (50-300rad(Si)/s): 100krad(Si)
○ LDR (0.01rad(Si)/s): 75krad(Si)
The ISL7x061SEH devices operate across the
military temperature range from -55°C to +125°C and
are available in a 14 Ld hermetically sealed Ceramic
Dual Flatpack (CDFP) package or in die form.
