SiLM2661 - Battery Pack Front-End Charge/Discharge High-Side NFET Driver

Download the SiLM2661 datasheet PDF. This datasheet also covers the SiLM2660 variant, as both devices belong to the same battery pack front-end charge/discharge high-side nfet driver family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • 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.

SiLM2660/SiLM2661 Battery Pack Front-End Charge/Discharge High-Side NFET Driver GENERAL DESCRIPTION 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. The SiLM2660 has additional P-channel FET control to allow low-current pre-charge to a deeply discharged battery, and it also integrates a PACK+ voltage monitor for the host to sense the PACK+ voltage. The independent enable inputs allow charge and discharge FETs to be turned on and off separately, offering the great design flexibility for battery systems. The SiLM2660 is available in TSSOP-16 and SiLM2661 is available in SOP8 package.
