ND1130 Series

Dual H-Bridge Driver with Boost converter

The ND1130 is a dual H-bridge driver IC that uses a Bi-CMOS process with Boost converter. The boost voltage from a Li-ion battery or 5V power supply, and drive small piezoelectric actuators and haptic devices using two H-bridge drivers. The Boost converter has a built-in soft-start function to limit the inrush current at power-on. The dual H-bridge driver supports independent signal input between channels, improving controllability from the microcontroller. I/O signal freguencyis up to 300 kHz and can output a FAULT signal in the event of an error.

Applications

• Small piezo actuators
• Haptics devices
