Battery protection systems
A battery protection system includes a sensor, a primary protection circuit, coupled to the sensor, and a secondary protection circuit, coupled to the primary protection circuit and the sensor. The sensor is configured to generate a sense signal indicative of temperature in a battery pack when the sensor is activated. The primary protection circuit is configured to generate a synchronizing signal in a first state or a second state, sample the sense signal when the synchronizing signal is in the first state, and provide primary protection to the battery pack based on the sense signal. A secondary protection circuit is configured to be controlled by the synchronizing signal, sample the sense signal when the synchronizing signal is in the second state, and provide secondary protection to the battery pack based on the sense signal.
