What are the key features of DRV101TG3?
- Integrated PWM driver with internal oscillator for solenoid and proportional valve control without external switching transistors
- 1 A continuous and 2.3 A peak output current sink with built-in overcurrent and thermal shutdown protection for robust load driving
- 7-pin TO-220 package allows heatsink mounting for sustained high-power solenoid drive in industrial and automotive environments
What is DRV101TG3 used for?
The DRV101TG3 is designed to drive inductive solenoids, proportional valves, and relay coils in automotive body control, industrial fluid control systems, and factory automation equipment. Its integrated PWM oscillator eliminates the need for an external microcontroller PWM output, simplifying standalone solenoid on/off or proportional control designs. The overcurrent and thermal protection features ensure reliable operation in high-ambient-temperature environments where solenoid stall or wiring faults are possible.

Frequently Asked Questions
What output current levels does the DRV101TG3 support for solenoid drive applications?
The DRV101TG3 sinks up to 1 A continuous and 2.3 A peak output current, covering the range of small to medium-sized solenoids and proportional valves typically rated from 200 mA to 1 A at 12 V or 24 V supply rails in automotive and industrial fluid control systems.
How does the DRV101TG3's integrated PWM oscillator simplify proportional solenoid control circuit design?
The internal PWM oscillator in the DRV101TG3 generates the switching signal internally, so the designer needs only to apply a 0 V to 5 V analog control voltage to the input pin to set the duty cycle from 0% to nearly 100%, without requiring a microcontroller PWM peripheral or gate driver IC. This reduces the BOM to the DRV101TG3 plus a 100 nF decoupling capacitor and a flyback diode across the solenoid.
What protections does the DRV101TG3 include and how do they guard against solenoid faults?
The DRV101TG3 integrates both overcurrent shutdown (peak limit of 2.3 A) and thermal shutdown protection that activates at approximately 150°C junction temperature. If a solenoid winding short reduces load impedance below 6 Ω on a 12 V rail, the overcurrent limiter engages within microseconds, preventing device destruction and reducing the risk of wiring harness overheating in automotive body control units.
For a 24 V pneumatic valve driver on an industrial automation panel, what thermal management approach suits the DRV101TG3 TO-220 package?
Mounted on a standard TO-220 clip-on heatsink with 5°C/W thermal resistance, the DRV101TG3 dissipates up to 15 W at a 25°C ambient temperature while keeping junction temperature within the 150°C limit. For a 1 A solenoid drive at 24 V with 50% duty cycle, the device dissipates approximately 5 W, requiring a heatsink of only 2°C/W to 3°C/W in a 60°C industrial panel enclosure.
