AAHS298B Radiation Tolerant 8-channel Source Driver The AAHS298B is part of Microsemi’s new family of Radiation Tolerant products aimed at the aerospace and defense markets. The AAHS298B is a RadiationTolerant source driver with eight non-inverting channels, with internal thermal shutdown. Capable of providing an interface from TTL, 5V or 12V logic systems to relays, motors, solenoids, and other loads, this device adds the additional benefit of an internal thermal shutdown and output transient protection/clamp diodes with sustaining voltages to 75V. Each output is capable of sourcing 700mA with a withstand voltage of 75V over the full military temperature range. The thermal shutdown is intended to protect against over-current and soft-start occurrences. The AAHS298B is offered in 20-pin ceramic SOIC package with formed and flat leads. The AAHS298B has demonstrated tolerance to 100kRad Si total dose min , 50kRad Si ELDRS min , as well as immunity to latch-up and SEE tolerance. Available standard screening includes Level “S” or Level “B,” Other screening or processing in line with our capabilities can be supported to meet customers’ requirements. • 700mA Output Source Current • Zero Quiescent Off Current • Full Channel Isolation to Prevent Fault Propagation • Internal Ground Clamp Diodes • 75V Output Breakdown Voltage • TTL, 5V and 12V Logic Compatible • Internal Thermal Shutdown • Radiation tolerant to 100kRad Si Total Dose, 50kRad Si ELDRS • -55°C to +125°C Temperature Range • Available in 20-pin Ceramic SOIC with formed and flat Leads • QML-V and QML-Q Qualified • Relay/Solenoid Drivers • Lamp/LED Drivers • Stepper and/or Servo Motor Drivers • Redundant Power Distribution Product Highlight 1 AAHS298B 20 IN1 2 IN2 3 IN3 4 IN4 5 IN5 6 IN6 7 IN7 8 IN8 9 10 LX7710 11 20 LX7710 1 CH1 Power Bus CH2 Power Bus CH3 Power Bus CH4 Power Bus CH5 Power Bus CH6 Power Bus CH7 Power Bus CH8 Power Bus Figure 1 • Redundant Switchable Power Bus 2015 Microsemi Corporation- Analog Mixed Signal 9 IN8 8 IN7 7 IN6 6 IN5 5 IN4 4 IN3 3 IN2 2 IN1 20 AAHS298B 1 Pin Configuration and Pinout Pin Configuration and Pinout MSC-S AAHS298B 1MN37 YYWW XXX 20 GND 19 OUT1 18 OUT2 17 OUT3 16 OUT4 15 OUT5 14 OUT6 13 OUT7 12 OUT8 11 GND S20 PACKAGE Ordering Information Ambient Temperature Type Package -55°C to 125°C Hermetic CSOIC 20L Flat Lead -55°C to 125°C Hermetic CSOIC 20L 0°C to 70°C AAHS298B-07-4020A-EV AAHS298B-06-4020A-EQ AAHS298B-S-S20B-S SMD 5962-1523101VXA AAHS298B-S-S20B-B SMD 5962-1523101QXA AAHS298B-S-S20B-ENGR Flow Packaging Type Equivalent to Class V Equivalent to Class Q Tray QML-V QML- Q Tray Commercial Pin Description Pin Description Pin Number 1, 10 2-9 11, 20 12-19 Pin Designator Supply Voltage IN[1:8] GND OUT[1:8] Input Supply Voltage, both pins should be externally connected on the PCB to improve the internal current distribution and allow the device to safely provide the maximum 2800mA of continuous supply current. 8 Logic Inputs, TTL, CMOS & High Voltage 12V compatible.
