Abstract

The invention discloses a direct-current self-holding electronic switch module which comprises an overcurrent and short-circuit protection circuit, a module off control circuit, a module on control circuit, a main loop switch circuit, an auxiliary loop switch circuit, an anti-reverse charging circuit, an input interface Pin, an output interface Pout and a control signal interface P1. The lithium primary battery has the characteristics of simple circuit, high reliability, low self power consumption, small size, light weight, low cost, good impact resistance and the like, and can be used in a small lithium primary battery needing high impact resistance.

Description

technical field [0001] The invention belongs to the field of switch control, in particular to a DC self-maintaining electronic switch module. Background technique [0002] In a lithium primary battery pack, a switching device with impact resistance, short circuit protection function, low power consumption, low driving signal power, self-maintaining switching state, and short circuit protection function is required. [0003] The function of this device is that when the lithium primary battery is stored for a long time, the battery output is turned off, and the power consumption of the switching device is low; The state can be maintained to reduce the power consumption of the turn-on signal; in the event of an output short circuit, the switch can immediately close the main circuit to protect the main circuit devices; at the same time, it needs to meet the requirements of high impact resistance during transportation and use. [0004] At present, the commonly used technical mea...
