Перепутал авто зарядки и подал вместо 5 в. - 12 в.
Вскрытие показало горелую деталь К12d. Поиск в интернете результатов не дал.
Прошу помочь с идентификацией .
Фото прилагаю.
Обрезанные провода от АКБ.
DC/DC преобразователь - скорее всего 5V->3.3V. Первое - название какое нибудь у этого DVR есть? Типа mekasonikc или panashiba 😁. А если серьезно - желательно “снять” горелый элемент с платы и сделать фото дорожек под ним - тогда возможно получится идентифицировать его - или во всяком случае подобрать что туда станет.
Очень похоже на контроллер зарядки аккумулятора. Возмите даташит например на LTC4054 и сравните схему включения с Вашим чипом.
