Abstract
A programmable battery protection system. Implementations may include: a battery and a battery protection integrated circuit (IC) coupled with the battery that includes a reference voltage circuit, a variable resistor circuit coupled with the reference voltage circuit, and only two field effect transistors (FETs) coupled with the overcurrent detection circuit and with the battery. The reference voltage circuit and the variable resistor circuit may be configured to cause a current sense signal of the system to vary substantially linearly with changes in a supply voltage of the system.
