Title:
BATTERY CONSUMPTION DETERMINATION CIRCUIT AND WIRELESS COMMUNICATION UNIT
Document Type and Number:
Japanese Patent JP2022001841
Kind Code:
A
Abstract:
To provide a battery consumption determination circuit and a wireless communication unit capable of suppressing excessive battery consumption by a pseudo load section.SOLUTION: A battery consumption determination circuit 100 includes: a wireless communication unit 102 which is connected to a power supply line 110; a pseudo load unit 103 which has a load equivalent to that of the wireless communication unit 102; a voltage detection unit 105 which detects the voltage of the power supply line 110; and a control unit 101 which determines the consumption of a battery 107 on the basis of at least one of a voltage value detected by the voltage detection unit 105 when the wireless communication unit 102 is in an operating state, and a voltage value detected by the voltage detection unit 105 with the pseudo-load unit 103 connected to the power supply line 110 when the wireless communication unit 102 is in a non-operating state. The control unit 101 resets a measurement timer 101b for periodically detecting the voltage value based on the pseudo load unit 103 in response to the detection of the voltage value based on the wireless communication unit 102.SELECTED DRAWING: Figure 2
