Abstract

The invention discloses a cell in-place detection circuit for a simulation circuit apparatus. The cell in-place detection circuit is characterized by comprising a pulse generating circuit for generating and outputting pulse signals, a cell sampling circuit for obtaining cell state information according to the pulse signals generated by the pulse generating circuit, and a signal processing circuit for determining whether a cell is at an in-place state according to the information obtained by the cell sampling circuit. The advantages are as follows: the circuit structure is simple, the cost is low and whether the cell is in-place can be monitored real time.

Description

technical field [0001] The invention relates to a battery in-position detection circuit, in particular to a circuit for detecting whether a battery in a pure analog circuit device is in-position. Background technique [0002] In electronic devices with charging functions, it is usually necessary to detect and monitor whether the battery is in place in real time. Using a power supply controlled by a digital chip, the charging circuit can be turned off at regular intervals, and then check whether the battery port has voltage to determine whether the battery is in place. But in the power supply of pure analog circuit, this method will not work. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the battery in the analog circuit equipment in the prior art cannot realize the in-position detection, and propose a battery in-position detection circuit for the analog circuit equipment. The circuit has a simple structure, low cost, a...
