Advanced high performance semiconductor devices can be sensitive to Single Event Latch-Up (SEL)effects when exposed to radiation in a space environment. Even though SEL is a very rare event, it canlead to device destruction and therefore must be mitigated to ensure the reliability and success of themission. Therefore, mission critical space applications that may be susceptible to SEL, should includeprotection devices such as a Latch-Up current Limiter (LCL).

The LCL is the best solution for power lines protection for advanced high performance electronics suchas ASICs, FPGAs (Actel, Xilinx,…) and memory banks in space applications: sciences and deep spacemissions, Earth observation, navigation, launchers and manned space vehicles.

The 3DPM0168-2 LCL Module monitors the powersupply line of radiation sensitive devices and switchesthem off instantaneously in case of “radiation inducedSEL” or high-current events in order to protect thedevice from over current and overheating.

The LCL Module offers two adjustable thresholdcurrents: to control device Run & Standby currents andtwo operating modes: Automatic reconnection withadjustable delay or reconnection through ON/OFFcommand.

Featuring specific radiation effect mitigation techniquesand utilizing space design derating rules, the3DPM0168-2 Latch-up Current Limiter is an ITAR Freeproduct and features a SEL/SEE LETth of 80MeV.cm2/mg and a TID of 50krad (Si).

PIN DESCRIPTION

Vin Input voltage used to power the LCL output load

Vout Protected voltage provided to the sensitive load

GND Ground pin

ON/OFF External command to switch ON (high level) or OFF (low level) the LCL

Prot_Status Digital output signal which reflects the current LCL status (Low=LCL not tripped, High=LCL tripped)

Run/Stb External input command to select the RUN protection current (high level) or the STANDBY protection current (low level)

VauxAuxiliary supply used to power the internal control circuit. Minimum Vaux voltage is 3.3V. When above 5.5V,a serial resistance must be inserted in series with Vaux pin. Can be connected to Vin when Vin is between 3.3V and 5.5V

Lim_Run Used to adjust the RUN protection level. Adjustment performed by connecting an external resistor between the pin and Lim_Stb pin

Lim_StbUsed to adjust the STANDBY protection level. Adjustment performed by connecting an external resistor between this pin and ground

Adj_RestartUsed to adjust the automatic reconnection delay. Adjustment performed by connecting an external capacitor betweenthis pin and ground. Use a short to inhibit the automatic reconnection mode
