Typical Applications
TMP816PWR is suitable for 6 applications: Server Cooling Fans, Power Supply Cooling Fans, Industrial Equipment Cooling, Automotive Cabin Fans, HVAC Blowers, Consumer Electronics Cooling.
Server Cooling Fans
The TMP816PWR drives large server cooling fans with high air volume and current. Its 6-16V supply range and 20mA output current are ideal for controlling external PNP-NMOS transistors that switch high motor currents. The adjustable current limit protects the motor and power stage, while PWM control enables variable speed for thermal management. This results in efficient, quiet operation essential for data centers.
Recommended
Power Supply Cooling Fans
In power supplies, the TMP816PWR drives cooling fans that dissipate heat from transformers and semiconductors. Its high-efficiency drive reduces power loss, and the low-saturation external transistors minimize heat generation. The device's wide supply range accommodates varying input voltages, and the adjustable current limit ensures safe operation under different load conditions. This makes it a reliable choice for ATX and industrial power supplies.
Recommended
Industrial Equipment Cooling
The TMP816PWR is used in industrial equipment such as motor drives, inverters, and welding machines to drive cooling fans. Its robust operating temperature range of -30Β°C to 95Β°C suits harsh environments. The device's ability to drive large current motors with minimal external components simplifies design and reduces BOM cost. PWM control allows precise thermal management, improving system reliability and longevity.
Recommended
Automotive Cabin Fans
Although not AEC-Q100 qualified, the TMP816PWR can be used in automotive cabin fans where the temperature range is within -30Β°C to 95Β°C. Its high-efficiency drive reduces battery drain, and the adjustable current limit protects the motor. PWM control enables variable speed for passenger comfort. Designers should ensure the supply voltage (6-16V) matches the vehicle's electrical system.
Recommended
HVAC Blowers
The TMP816PWR drives blowers in HVAC systems, providing efficient and quiet operation. Its single-phase full-wave drive with external PNP-NMOS transistors achieves low saturation voltage, reducing power loss. The adjustable current limit prevents overcurrent damage, and PWM control allows variable speed for energy savings. The device's wide supply range accommodates different AC/DC power architectures.
Recommended
Consumer Electronics Cooling
In consumer electronics like gaming consoles and audio amplifiers, the TMP816PWR drives cooling fans to manage heat. Its low noise and high efficiency are beneficial for quiet operation. The device's small TSSOP package saves PCB space, and the adjustable current limit ensures safe operation. PWM control enables dynamic fan speed based on system temperature, improving user experience.

- Lower supply voltage range (vs DRV10970)
Design Notes
Place the TMP816PWR close to the external power transistors to minimize gate drive loop inductance. Use wide traces for the power path and add a 0.1uF ceramic capacitor near the VCC pin. Ensure a solid ground plane for heat dissipation and noise reduction.
The TMP816PWR itself dissipates little power, but the external PNP-NMOS transistors may generate significant heat. Ensure adequate heatsinking for the power stage. The device's operating temperature range is -30Β°C to 95Β°C, so keep the ambient temperature within this limit.
Do not exceed the supply voltage of 16V. Set the current limit threshold appropriately using the ISET pin to protect the motor. Ensure the PWM input is properly filtered to avoid false triggering. Verify the external transistor's base/gate drive requirements match the 20mA output capability.
Compliance Information
