HY2550
HY2550 Series Features
- High-accuracy voltage detection circuit for 3/4/5 Cell Application
- Charge overcurrent protection
- Three-level discharge overcurrent protection
- Delay time:
- Delay times are set by external capacitors respectively at CCT pin and CDT pin for overcharge detection, /charge overcurrent detection and overdischarge detection/discharge overcurrent detection voltage 1
- Delay times are set internally for discharge overcurrent detection voltage 2 (1ms) and discharge overcurrent detection 3 (300μs)
- Cell number selection: SEL pin is used to select either 3 cells or 4 cells in use. SEL5 pin is used to select 5 cells in use when SEL pin is also set to “1”
- Charge/discharge operation can be controlled via the CTL pin
- 0V Battery Charge inhibition
- High voltage withstand range: Absolute maximum rated level：28V
- Wide operating temperature range：-40℃ to +85℃
- Low current consumption:
- Operation mode 12μA typ., 30μA max. (VCn = 3.5V)
- Power-down mode 1.2μA typ., 2.0μA max. (VCn = 2.0V)
- Small package:16-pin TSSOP
- Halogen free green product
