Rating for Rad Hard Switches Contact MSK for MIL-PRF-38534 Qualification Status DESCRIPTION: The MSK6000RH is a radiation hardened dual 5A high side switch module with a current sensing output. Each switch is independently controlled with 5V logic and can switch up to 5A maximum current. Each switch has its own independent ground reference. The current monitor outputs provide a simple method for monitoring the current in each switch. The device is designed for space applications where quality, performance and low weight are a must. The MSK6000RH is packaged in a hermetic 26 pin flatpack.

F 10/14 APPLICATION NOTES PIN FUNCTIONS TYPICAL APPLICATION CIRCUIT VIN - The VIN pins are connected to sources of MOSFETs. They provide the voltage supply that is switched to the output pins. High di/dt can be present at these pins during switch on and off transitions. Decoupling capacitors are recommended to minimize voltage spikes. VCC - The VCC pins power the current sense amplifier. The VCC pins should be connected to low impedance positive supply source. VOUT - The VOUT pins connect to drains of internal MOSFETs and are the device power outputs. CTL - The CTL pins connect to the high side switch enabling circuits. When a logic high voltage is present, the high side switches turn on passing power from VIN to VOUT. The CTL pin threshold has no hysterisis. It operates in a linear region between 2.0V typical (OFF) and 2.7V typical (ON) at 25°C, 1.3V typical (OFF) and 2.2V typical (ON) at 125°C, and 2.6V typical (OFF) and 3.0V typical (ON) at -55°C. Input signals with fast transitions are recommended to prevent excessive power dissipation. HIGH VIN APPLICATION CIRCUIT IMON - The IMON pins connect to the output of the internal RH6105 current sense amplifiers. Voltage drop across internal current sense resistor is amplified and a scaled current is sourced from the IMON pin. The ratio of IMON current to source current is 0.20mA/A. When terminated with a 5KΩ resistor the output voltage is 1V/A. GND - The GND pins are the reference for each driver circuit. Each channel has it's own ground. The control input signals and current sense outputs are referenced to the respective grounds. CASE - The CASE connection pins provide an electrical connection to the MSK6000RH package. They are electrically isolated from the internal circuitry. TOTAL DOSE RADIATION TEST PERFORMANCE Radiation performance curves for TID testing have been generated for all radiation testing performed by MS Kennedy. These curves show performance trends throughout the TID test process and are located in the MSK6000RH radiation test report. The complete radiation test report is available in the RAD HARD PRODUCTS section on the MSK website. 3 8548-114 Rev. F 10/14 APPLICATION NOTES VOUT RISE TIME CONTROL The output rise time of the MSK6000RH and the associated surge currents can be controlled over a wide range using a few external components as shown in the smplified schematic below. Power dissipation in the MSK6000RH can increase during turn on or bus voltage transients and should be considered. The circuit below performs the rise time control function by controlling the voltage drop VR across RBAL. Assuming a constant current to linearly change the output capacitance, the MSK6000RH rise time is approximated by the following equation: dVOUT VRBAL = Where VRBAL=VC - VTHRESHOLD dt ßQ1 x RBAL x CFB VOUT RISE TIME CONTROL CIRCUIT 4 8548-114 Rev.
