BATTERY MANAGEMENT DEVICE, SECONDARY BATTERY DEVICE, AND VEHICLE
First Claim
1. A battery management device, comprising:
- a power source supply management module to which a power is supplied from an external power source;
a power source supply circuit to which a power is supplied from the power source supply management module via a first power source input terminal;
a latch circuit configured to be operated by a power supplied from the power supply circuit or a power supplied via a second power source input terminal;
a control circuit configured to output a logic signal that sets a shutdown signal output from the latch circuit to a logic signal input terminal; and
a logic communication circuit to which a logic signal is supplied via the logic signal input terminal and which supplies the logic signal to a set signal input terminal of the larch circuit, whereinthe shutdown signal output from the latch circuit is set to an operation maintenance level when the logic signal is set to a second level from a first level.

Abstract
According to one embodiment, a device includes a power management module to which a power is supplied from an external power source, a power source supply circuit to which a power is supplied from the power management module via a first input terminal, a latch circuit configured to be operated by a power supplied from the power supply circuit or a power supplied via a second input terminal, a circuit configured to output a logic signal that sets a shutdown signal output from the latch circuit to a third input terminal, and a logic communication circuit to which a logic signal is supplied via the third input terminal and which supplies the logic signal to a forth terminal of the larch circuit. The shutdown signal output from the latch circuit is set to an predetermined level when the logic signal is set to a second level from a first level.
