The SiLM2660/SiLM2661 is a low-power, high-side N-channel FET driver for battery charge/discharge system control.

A high-side control avoids ground disconnection in the system and allows continuous communication between the battery pack and host system.

High side NFET driver with fast turn-on and turnoff times for battery protection.
Pre-charge PFET driver provides a currentlimited pre-charge function for depleted cell-pack (only for SiLM2660).
Independent enable control for charging and discharging.
Scalable external capacitor-based charge pump to accommodate a different range of FETs in parallel.
High voltage tolerant (100 V absolute maximum).
Internal switch to enable pack-voltage sensin.
