Arduino 8 Channels High-Side Switch
The project presented here is a high-side switch (8 channels) with MOSFET output. The Arduino board consists of an Arduino-compatible microcontroller ATMEGA328 and TPD2015FN – 8 Channels MOSFET switch. All 8 inputs of TPD2015FN are TTL compatible. The project is suitable for driving inductive and resistive loads such as industrial programmable logic controllers, motors, and lamps in factory automation equipment, etc. This product has built-in overcurrent and over-temperature protection functions, which contribute to improved stability of the system.
Features
- Power Supply Load 8V to 40V
- 8-channels of N-channel MOSFET and charge pump are built-in.
- This IC can drive the power load directly.
- Built-in protection against over temperature and over current.
- 8-channels access enables space-saving design.
- Low on resistance: 0.55Ω (max) @ VDD = 12V, IOUT = 0.5A, Tj = 25℃ (per channel)
- Parallel operation is possible.
- Over current protection operating time 3mS
- Over current protection Threshold 1.8A
- Over temperature detection Threshold 175C
- Switching time 6uS
- PCB Dimensions 41.28 X 33.02 mm
TPD2015FN is a high-side switch (8-channels) with MOSFET outputs. This is the monolithic power IC that can be driven directly from CMOS, TTL logic circuitry (MCU, etc.) and has over-current and over-temperature protection features.
