Battery protection and zero volt battery recovery system for implantable medical devices |
| abstract |
A circuit is disclosed that can be used to protect a rechargeable battery and that can be used to reliably charge a rechargeable battery even from a zero volt condition. This is particularly useful when employed in an apparatus. The circuit includes two charging paths, the first path is for charging the battery at a relatively low voltage when the battery voltage is below a threshold, and the second path is The battery is charged with a relatively high current when the battery voltage exceeds a certain threshold. A passive diode is used in the first stagnation charging path, which allows slag charging even when the battery voltage is too low for reliable gating. On the other hand, a gate controllable switch (preferably a PMOS transistor) is used in the second high current charging path when the voltage is higher, so that this switch can be gated more reliably. The second diode between the two paths ensures that there is no leakage to the substrate via the gate controllable switch during the throttling charge period. A load is connected to the battery via the switch, preferably via a second switch that is specifically used to disconnect the load. [Selection] Figure 7 |
