на ключах написано 1025(этот сдох совсем, вздулся, в одну сторону не крутит совсем) и 2029 , этот еще жив , но крутит вяло.
Что это за ключи? Чем можно заменить ?
Судя по схеме включения в одном корпусе два N-канальных ключа, в другом два P-канальных ключа.
Заменить можно на:
IRF7301, IRF7311, IRF7313 - два N-нанальных ключа
IRF7304, IRF7314, IRF7316 - два P-канальных ключа
Корпус у которого 1 и 3 выводы подключены к минусу питания N-канальные ключи, к плюсу P-канальные ключи.
Возможно еще были поврежнены порты микроконтролера.
Большое спасибо за инфо …

Очень маловероятно. 1 к 100.
