R1: The benchmark power supply resistance; the voltage voltage circuit with the internal resistance of the IC, control the level of the internal overcharge and overdering voltage comparators; it is generally more in the resistance value of 330Ω, 470Ω; Long and Kuanlai represents the size of the component, such as 0402 packaging identification of the length and width of this component is 1.0mm and 0.5mm, respectively, and the resistance value will be identified by numbers. The resistance value is 47000Ω, that is, 47kΩ (the third digit indicates the number of 0 digits after the first two digits).
R2: Overcurrent and short -circuit detection resistors; by detecting the current of the VM -end voltage control the protective board, poor welding and damage will cause the battery overcurrent and short -circuit without protection. The general resistance value is 1kΩ and 2kΩ.
R3: ID recognition resistance or NTC resistance (introduced earlier) or both.
Summary: The resistance is a black patch in the protective board. It can measure its resistance value with a multimeter. When the packaging is large, the resistance value will be represented by numbers. The method of indicating the method is as described above. Of course, the resistance value is generally deviated. The resistance has accuracy specifications. For example, the 10kΩ resistance specification is +/ -5 % accuracy, and its resistance value is 9.5kΩ -10.5kΩ.
C1, C2: Because the voltage ends of the capacitor cannot be changed, the voltage voltage and filtering are instantaneous. Summary: The capacitor is yellow patch in the protective board. The encapsulation form is 0402, and there are also a few 0603 packaging (1.6mm long, 0.8mm wide); the resistance value of the multimeter is generally infinite or MΩ. Power consumption is large, and there is no self -recovery in short circuit. FUSE: Ordinary Fuse or PTC (Positive Tempeature Coefficient's abbreviation, which means positive temperature coefficient); prevent the occurrence of unsafe large current and high temperature discharge, where PTC has a self -recovery function.
Summary: FUSE is generally white patch in the protective board. Litte provides FUSE to identify character D-T on FUSE. The character indicates that FUSE can withstand the rated current. For example 5A, etc.
U1: Control IC; all the functions of the protective board are realized by monitoring the voltage difference between VDD-VSS and the voltage difference between VM-VSS to control the C-MOS execution switching action.
COUT: Excess control; control the switch of the MOS tube through the MOS tube T2 meter voltage.
DOUT: Pass, overcurrent, short -circuit control end; control the switch of the MOS tube through the MOS tube T1 gate voltage.
VM: Overcurrent, short -circuit protection voltage detection end; through the detection of VM -end voltage to implement circuit overcurrent and short -circuit protection
