Description
- Battery Fast Charge Controllers
- The MC33340 and MC33342 are monolithic control IC’s that are specifically designed as fast charge controllers for Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH) batteries. These devices feature negative slope voltage detection as the primary means for fast charge termination. Accurate detection is ensured by an output that momentarily interrupts the charge current for precise voltage sampling. An additional secondary backup termination method can be selected that consists of either a programmable time or temperature limit.
- •Negative Slope Voltage Detection with 4.0 mV Sensitivity
- •Accurate Zero Current Battery Voltage Sensing
- •High Noise Immunity with Synchronous VFC/Logic
- •Programmable 1 to 4 Hour Fast Charge Time Limit
- •Programmable Over/Undertemperature Detection
- •Battery Over and Undervoltage Fast Charge Protection
- •Power Supply Input Undervoltage Lockout with Hysteresis
- •Operating Voltage Range of 3.25 V to 18 V
- •177 seconds Fast Change Holdoff Time (MC33340)
- •708 seconds Fast Change Holdoff Time (MC33342)
- •Pb−Free Packages are Available
