Microchip Technology Inc. expanded its portfolio of automotive semiconductors with the release of two new 3-phase brushless DC (BLDC) motor gate drivers designed to provide a complete motor control and drive package for vehicles and industrial applications.
The two motor gate drivers come with an integrated power module, LIN transceiver and sleep mode and can power Microchip’s digital signal controllers (DSCs) and PIC microcontrollers (MCUs) complementing its control algorithms by driving MOSFETs, sensing current, preventing short circuits, outputting zero crosses, controlling dead time and blanking time and monitoring for fault conditions.
As a result, Microchip said the combination of these chips provides a complete motor control and drive package that can be used in either industrial applications or automobiles.
“The automotive and industrial markets continue to demand motor drive and control solutions with higher performance, integration and flexibility, along with reduced cost, complexity and time to market,” said Bryan J. Liddiard, marketing vice president of Microchip’s Analog and Interface Products Division, in a statement. The pairing of these motor gate drivers along with Microchip’s DSCs and MCUs offers a way to do this, Liddiard added.
Microchip claims the devices feature a drivers’ 150 degrees Celsius ambient temperature, low sleep current of 5 microamps and the LIN transceiver make it suited for automotive designs especially those that operate under the hood or need to reduce key-off power consumption.
The two chips, dubbed MCP8025/MCP8026 are available now for sampling and volume production with prices beginning at $2.13 each in 5,000 unit quantities.
