Abstract
Various embodiments relate to protection circuits. A protection circuit may include a first node for coupling to a first battery and a second node for coupling to a second battery. The protection circuit may also include a first path coupled between the second node and the first node and including a diode. The protection circuit may also include a second path coupled between the first node and the second node. The second path may include a first stage coupled to the first node and including a first number of thermistors coupled in parallel. The second path may also include a second stage coupled between the first stage and the second node and including a second number of thermistors coupled in parallel, wherein the first stage may be coupled in series with the second stage. Associated methods, systems, and devices are also disclosed.
