IN Brief:
- NOVOSENSE is showing H-bridge and smart low-side drivers at PCIM Europe 2026.
- The portfolio includes NSD7305, NSD7308, NSD7309, NSD5614, and NSD5624 devices.
- Motor-control designs are adding diagnostics, current sensing, EMI controls, and simpler digital interfaces.
NOVOSENSE Microelectronics is showcasing a low-voltage motor driver portfolio at PCIM Europe 2026 for industrial automation, smart appliances, and intelligent terminal applications.
The portfolio includes the NSD7305, NSD7308, and NSD7309 H-bridge motor drivers, alongside the NSD5614 and NSD5624 four-channel smart low-side driver series. The devices bring together higher integration, protection, diagnostics, current sensing, and electromagnetic interference controls for compact motor and load-driving systems.
The NSD7305 and NSD7308 are 40V brushed DC motor drivers supporting H-bridge and half-bridge configurations. Both include configurable output slew-rate control and spread-spectrum clocking to tune EMI behaviour in motor-drive systems. Integrated current mirror sensing removes the need for external sense resistors, reducing bill-of-materials count and simplifying PCB layout.
The two devices include VM voltage monitoring, overcurrent protection, overtemperature protection, open-load diagnostics, and short-circuit diagnostics. The NSD7305 supports up to 21A peak current with 47mΩ RDS(ON), while the NSD7308 supports up to 12A peak current with 84mΩ RDS(ON). Hardware and SPI interface versions are supported.
The NSD7309 addresses compact motor-control applications with a single-channel H-bridge driver supporting up to 8A peak current and 120mΩ RDS(ON). It supports PWM control, integrated current regulation, undervoltage protection, overvoltage protection, overcurrent protection, and overtemperature protection.
For industrial PLC and factory automation systems, the NSD5614 and NSD5624 smart low-side driver series support PWM and SPI control, open-load and short-to-ground diagnostics, and channel parallel operation for higher current capability. SPI daisy-chain capability can reduce the number of digital isolation channels required in industrial control systems, helping simplify compact control-module designs.
Low-voltage motor control is becoming more capable as automation spreads into smaller machines, appliances, terminals, and distributed industrial equipment. Designers need compact drivers that integrate protection and diagnostics while remaining manageable for EMC and thermal design. Current sensing and slew-rate control at driver level give engineers more control over switching behaviour without adding large amounts of external circuitry.
Diagnostics are also moving closer to the machine edge. Developments such as in-sensor AI for vibration monitoring show condition information being captured nearer to the equipment itself. Motor drivers are following a parallel path by bringing protection, fault detection, and current information closer to the actuator stage.
Industrial control architectures remain constrained by board space, isolation cost, and wiring complexity. SPI daisy-chaining in smart low-side drivers is therefore more than a convenience feature; it can reduce isolation-channel count and make multi-output PLC modules easier to design. NOVOSENSE’s PCIM portfolio reflects the steady integration of motor-control building blocks, with low-voltage motion systems becoming smarter, more protected, and more visible to the controller.
