- Driving solenoids
- Driving stepper motors
- Driving LED displays
- Driving incandescent lamps
Features
- High output voltage: 50V (min)
- High output current: 500mA (max) per channel
- 7 independent channels
- Input voltage range compatible with TTL and 5V CMOS logic
- Internal clamp diodes for inductive load driving
- Thermal shutdown protection
- DIP-16 package
Benefits
- Simplified interface between logic circuits and high-power loads
- Reliable driving of inductive loads due to integrated clamp diodes, protecting the driver from voltage spikes.
- Protection against over-temperature conditions through thermal shutdown, enhancing system reliability.
- Reduced component count by integrating multiple driver channels into a single package, saving board space and cost.
- Versatile application due to high voltage and current driving capabilities.
Additional Details
The TD62706F incorporates internal clamp diodes connected between each output and the ground to protect against inductive kickback when driving inductive loads such as relays and solenoids. The device operates with a supply voltage typically ranging from 4.75V to 5.25V. The input logic is designed to be compatible with both TTL and 5V CMOS logic levels, providing flexibility in interfacing with different control circuits. The maximum power dissipation of the entire package is limited, so care should be taken to ensure proper heat sinking is provided if all channels are driven at maximum current simultaneously. The operating temperature range typically spans from -40°C to +85°C.
