description The utility model relates to an intrinsic safety type mobile phone and belongs to the technical field of mining communication devices. The intrinsic safety type mobile phone comprises a radio frequency unit, a logic unit and a mobile phone battery. A battery protection device is connected onto the mobile phone battery and comprises a battery protection circuit DW01, a fuse protector and a metal oxide semiconductor (MOS) tube 8205 A. The fuse protector is arranged between the cathode end of the mobile phone battery and the MOS tube 8205A and used for preventing overcurrent of the battery. The power supply end of the battery protection circuit DW01 is connected with an anode of the mobile phone battery through a sampling resistor, the over discharge detection circuit output end of the battery protection circuit DW01 is connected with the GATE 2 end of the MOS tube 8205A, and the over charge detection circuit output end of the battery protection circuit DW01 is connected with the GATE1 end.
