HY2540
HY2540 Series Features
- High-accuracy voltage detection circuit for 3/4 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 battery cells in use or 4 battery cells in use.
- 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.
