STMicro STSPIN32G0 是一系列新的高級(jí)三相電機(jī)控制器，可變電壓范圍為 45V 至 600V，通過(guò)集成 MCU 和電機(jī)驅(qū)動(dòng)器擴(kuò)展了 STMicro 的器件產(chǎn)品組合。

新系列將三半橋柵極驅(qū)動(dòng)器與基于 Arm Cortex-M0+ 的 [STM32G0] 微控制器相結(jié)合，能夠處理六步和磁場(chǎng)定向控制 （FOC） 算法。STSPIN32G0 系列的集成設(shè)計(jì)可節(jié)省成本，并“在不影響性能和穩(wěn)健性的情況下顯著減少 BOM 面積”。

STSPIN32G0 系列有兩個(gè)主要版本，低壓和高壓。低壓 3 相電機(jī)控制器包括一個(gè)穩(wěn)壓器、一個(gè)或三個(gè)分流器以及一個(gè)額定電壓為 45V、電流高達(dá) 0.6A 的柵極驅(qū)動(dòng)器。它們主要針對(duì)家用電器、電動(dòng)工具和無(wú)人機(jī)。高壓版本可以處理 250V 或 600V，使其適用于工業(yè)逆變器和風(fēng)扇。它們針對(duì)家用電器、空調(diào)、家用和工業(yè)冰箱、工業(yè)泵和工業(yè)自動(dòng)化。
