- Delivers excessive energy density with STDRIVE101 3-phase gate-driver IC and very low energy consumption in sleep mode
- Assembled boards now out there in eSTore
The EVLDRIVE101-HPD (Excessive Energy Density) motor-drive reference design by STMicroelectronics packs a 3-phase gate driver, STM32G0 microcontroller, and 750W energy stage on a round PCB simply 50mm in diameter. The board options extraordinarily low energy consumption in sleep mode, beneath 1uA, and its tiny define can match immediately in gear like hairdryers, handheld vacuums, energy instruments, and followers. It additionally suits simply into drones, robots, and drives for industrial gear reminiscent of pumps and process-automation techniques.
Constructed with ST’s sturdy and compact STDRIVE101 3-phase gate driver, the reference design offers flexibility to decide on the motor-control technique, reminiscent of trapezoidal or field-oriented management (FOC), with sensored or sensorless rotor-position detection. The STDRIVE101 IC comprises three-half bridges with 600 mA supply/sink functionality and operates from 5.5V to 75V to deal with any low-voltage software. The chip integrates voltage regulation for the high-side and low-side gate drivers and configurable drain-source-voltage (Vds) monitoring safety. It additionally supplies an exterior pin for selecting direct high-side and low-side gate inputs or PWM management.
Builders can make the most of the STM32G0 single-wire debug (SWD) interface to work together with the microcontroller, whereas help for direct firmware replace permits making use of bug fixes and new options.
The ability stage of the EVLDRIVE101-HPD reference design options STL220N6F7 60V STripFET F7 MOSFETs, which protect effectivity with their 1,2mΩ typical Rds(on), easing plug-and-play connection of the motor. Further options embody fast-acting power-on circuitry that disconnects the ability supply when idle to save lots of power and lengthen operation in battery-powered functions. Safety constructed into the driving force IC ensures system security and effectivity, together with the Vds monitoring of the power-stage MOSFETs, in addition to under-voltage lockout (UVLO), overtemperature safety, and cross-conduction prevention.
The EVLDRIVE101-HPD is able to use out of the field and is on the market now from the eSTore, for $92.00.
