H-Bridge 4 Click Board™

How Does The H-Bridge 4 Click Board™ Work?

The main component of the H-Bridge 4 Click Board™ is the AP1010AEN from AsahiKASEI (AKM), which is a two channel H-Bridge motor driver compatible with motor operating voltage up to. This IC is an efficient integrated H-bridge driver, with very low RDS ON output per switch. H-bridge in general, allows the current to flow in one or another direction. The output stages consist of four n-channel mosfets in H-bridge configuration. The outputs are protected against short circuits and over temperature. The bridge is controlled using the inputs IN1, IN2, IN3, and IN4, which are witer to the AN, RST, INT, and PWM pins on the mikroBUS™, respectively.

Its motor operating voltage range is between 6.0V～18V and control power supply is unnecessary. When it comes to its maximum output current (DC) its 0.7A @Ta=25°C and it has H-Bridge On-Resistance, which equals RON(TOP+BOT) = 1.1Ω @Ta=25°C. The Click board™ has an onboard motor voltage supply selection switch, although it is recommended to use the external power supply. The AP1010AEN also has the possibility of a parallel connection, under voltage lockout circuit and the thermal shutdown circuit. The Overcurrent protection circuit is disabled when DIS OCP terminal = "H" and the operating Temperature Range is between -30°C～85°C.

When the internal temperature of the IC reaches the specified temperature (TTSD=155°C), and the H-Bridge driver outputs Hi-Z. When the internal temperature after the detection is lowered about 30°C (TTSDHYS), the driver resumes operation. Restart Temperature = TTSD - TTSDHYS

When the current of 2.6 A or more continues to flow to the H - Bridge driver for 10 μs, all H - Bridge driver outputs are set to Hi - Z, and automatically return after 200 ms. Over current protection circuit can be used by setting the DIS OCP terminal to L level. When not using the overcurrent protection circuit, connect the DIS OCP terminal to the VDC terminal.
