Frequently Asked Questions
What battery chemistry does the BQ2002ESN support?
The BQ2002ESN supports NiCd and NiMH rechargeable battery chemistries, designed for 1 to 4 cells at 1.2V per cell. It uses negative delta-V (NDV) voltage detection and optional temperature sensing to safely terminate fast-charge cycles.
What is the supply voltage range for the BQ2002ESN?
The BQ2002ESN operates from a 4.5V to 7V DC supply voltage, making it suitable for wall adapter or regulated DC input designs in portable consumer and industrial equipment.
What package is the BQ2002ESN and how many pins does it have?
The BQ2002ESN comes in an 8-pin SOIC (Small Outline IC) package. The ESN suffix denotes the SOIC-8 package variant, offering a compact footprint ideal for space-constrained PCB layouts.
What are common alternatives to the BQ2002ESN?
Common alternatives include the BQ2003 (extended NiMH feature set), MAX712/MAX713 (Maxim fast-charge controllers), and LTC4011 (Linear Technology NiMH charger). These offer similar NDV termination but differ in cell count support and feature integration.
What is the operating temperature range of the BQ2002ESN?
The BQ2002ESN has a commercial-grade operating temperature range of 0°C to 70°C, suitable for indoor consumer electronics. For industrial applications requiring -40°C to 85°C, consider the BQ2002E variant.
