The FAH4820MPX is a direct driver designed for DC motors, specifically optimized for eccentric rotating mass (ERM) applications in mobile phones and handheld devices. It features a single-pin direct-drive mechanism that simplifies vibration control without the need for a PWM signal. The device can be enabled or disabled via an external HEN pin, and it allows for programmable motor drive voltage through an optional I¬=C interface. This motor driver operates with a low standby current of less than 1 ¬µA and has a fast wake-up time, making it suitable for battery-powered applications. It supports nearly rail-to-rail output swing and includes protections against under-voltage, over-current, and over-temperature conditions. The FAH4820MPX is housed in a compact 10-lead molded leadless package (MLP) and is rated for an operating temperature range of -40¬8C to +85¬8C. It is intended for applications such as mobile phones, handheld devices, and keypad interfaces.
