ST公司的STSPIN840是紧凑的有刷DC马达驱动器,能同时驱动两个双向有刷DC马达,在4 x 4 mm QFN封装上集成了两个控制逻辑和全保护低RDSon两个全桥功率级,工作电压从7V到45V,最大输出电流1.5Arms,全保护包括非耗散过流保护,短路保护,欠压锁住和热关断.主要用在工业自动化和服务机器人,医疗和保健,ATM,舞台照明,热打印机,纺织和缝纫机,销售机以办公和家庭自动化.本文介绍了STSPIN840主要特性,框图,应用框图和电路,以及马达驱动扩展板X-NUCLEO-IHM15A主要特性,电路图和材料清单.
The STSPIN840 is a compact brushed DC motordriver able to drive two bi-directional brushed DCmotors simultaneously. It integrates, in a verysmall 4 x 4 mm QFN package, both the controllogic and a fully protected low RDSon dual fullbridgepower stage.
Thanks to a dedicated PARALLEL input pin theparallel mode function can be enabled,transforming the device in an equivalent andmore powerful single full-bridge able to deliver upto 3Arms current at an equivalent HS + LS RDSonof 500 mohm.
The STSPIN840 embeds two independent PWMcurrent controllers (one for each full bridge) basedon user settable values of reference voltage andOFF time.The devices can be forced in a low consumptionstate reducing the total current consumption downto less than 45uA.
As with all other devices from the STSPIN family,the STSPIN840 integrates a complete set ofprotections for the power stages (non-dissipativeovercurrent, thermal shutdown, short-circuit andundervoltage lockout) making it a bulletproofsolution for the new wave of demanding industrialapplications.
STSPIN840主要特性:
Operating voltage from 7 to 45 V
Maximum output current 1.5 Arms
RDSon HS + LS = 1 ohmtyp.
Current control with adjustable OFF time
Current sensing based on external shuntresistors
Full protections set
– Non-dissipative overcurrent protection
– Short-circuit protection
– Undervoltage lockout
– Thermal shutdown
Parallel operation mode achieving single fullbridgeconfiguration with output IRMS = 3 Armsand RDSon HS + LS = 500 mohmtyp.
Low standby current consumption
STSPIN840应用:
Industrial automation and service robots
Medical and health care
ATM and money handling machines
Stage lighting
Thermal printers
Textile and sewing machines
Vending machines
Office and home automation

基于STSPIN840的双刷DC马达驱动扩展板X-NUCLEO-IHM15A
Dual brush DC motor driver expansion board based on STSPIN840 for stm32 Nucleo The X-NUCLEO-IHM15A1 dual brush DC motor driver expansion board is based on the STSPIN840 for STM32 Nucleo.
It provides an affordable and easy-to-use solution for the implementation of compact motor driving applications such as thermal printers, robotics and toys.
Thanks to the parallel operation, it can be easily converted to a single brush DC driver with double current capability.
The current limiters and complete set of protection features make it suitable for rugged applications.
The X-NUCLEO-IHM15A1 is compatible with the Arduino UNO R3 connector and most STM32 Nucleo boards.
马达驱动扩展板X-NUCLEO-IHM15A主要特性:
Voltage range from 7 to 45 V
Output current up to 1.5 Arms for each motor
Two independent current limiters with adjustable OFF time
Full protection set including: overcurrent, short-circuit, under voltage lock out and thermal shutdown
Parallel operation
Compatible with Arduino UNO R3 connector
Compatible with STM32 Nucleo boards
