The M38510/12903BPA is a dual peripheral driver from Texas Instruments, designed to translate low-level logic signals into high-current drive for loads like relays, lamps, and solenoids. Operating from 4.5V to 5.5V, it features open-collector outputs capable of sinking 300mA per channel. Housed in a rugged 8-CDIP ceramic package, it is qualified for military and aerospace applications, offering reliable performance from -55°C to 125°C.
- High Sink Current (300mA): Directly drives relays, solenoids, and lamps without external transistors.
- Open-Collector Outputs: Allows flexible connection to higher-voltage loads with external pull-up resistors.
- Military-Grade Temperature Range (-55°C to 125°C): Ensures operation in extreme environments.
- Ceramic DIP Package: Provides high reliability and resistance to thermal and mechanical stress.
Relay and Solenoid Driving
With 300mA sink capability, the M38510/12903BPA can directly drive relays and solenoids in industrial control systems, eliminating the need for external power transistors.
Lamp and LED Display Drivers
Its open-collector outputs can switch incandescent lamps or large LED displays in avionics panels, providing high current with simple logic control.
Motor Control in Military Equipment
In defense systems, it can drive small DC motors or stepper motor windings, with the wide -55°C to 125°C range ensuring operation in extreme conditions.
Logic-to-Power Interface in PLCs
It bridges the gap between 5V PLC logic and 24V industrial actuators, using an external pull-up resistor to the higher voltage rail.
Thermal Printer Head Driving
In ruggedized printers, it can sink the high current required by thermal print heads, with open-collector outputs allowing for precise control.
Automotive Load Switching
Although primarily military-grade, its high current and temperature range make it suitable for heavy-duty automotive applications like fuel injectors or headlamp relays.
