Nisshinbo’s new dual H-bridge driver with boost converter
Summary
Utilising a highly efficient Bi-CMOS process, it empowers systems with its capability to drive piezo actuators for camera modules and haptic devices. The H-bridge driver supports operating voltages from 7 V to 35 V and I/O signal frequencies up to 300 kHz, ensuring compatibility with demanding applications. It facilitates precise control of piezo actuators across two channels, with robust safeguards such as overcurrent protection, thermal shutdown, under-voltage lockout, and a fault indicator output. The ND1130 is ideal for modern, space-constrained designs like camera modules with small piezo actuators for controlling autofocus (AF), optical image stabilisation (OIS), and zoom capabilities, as well as miniature projectors, haptic feedback systems. A comprehensive circuit diagram and additional information simplify the design process, enabling faster time-to-market.
