TP5100 8.4V/4.2V Li-ion Battery Charging Module – 1 Pcs

 

The TP5100 is a versatile and efficient lithium battery management chip designed for charging a single lithium-ion cell or two lithium-ion cells in series. It is ideal for applications requiring a compact and reliable charging solution for lithium-ion batteries.

Features:

• Dual-Cell and Single-Cell Charging: Capable of charging dual-cell 8.4V or single-cell 4.2V lithium-ion batteries.
• Wide Input Voltage Range: Accepts input voltage from 5V to 15V DC.
• High Switching Frequency: Operates at a switching frequency of 400kHz.
• LED Indicators:
  • Red LED: Indicates charging status.
  • Blue LED: Indicates full charge or no battery.
  • Both LEDs Off: Indicates very low VIN or high-temperature shutdown.
• Built-In Protections: Includes input overcurrent, under-voltage protection, over-temperature protection, short circuit protection, battery temperature monitoring, and reverse battery protection.
• No External Schottky Diode Needed: Integrated design eliminates the need for an external anti-backflow Schottky diode.
• Mode Selection: Onboard solder jumper to set 1S (single-cell) or 2S (dual-cell) mode.
• External LED Option: Supports connection of an external bicolor LED.

Technical Specifications:

• Charging Capability: Dual-cell 8.4V or single-cell 4.2V
• Input Voltage: 5V-15V DC
• Switching Frequency: 400kHz
• LED Indicators:
  • Red LED: Charging indicator
  • Blue LED: Full charge/no battery indicator
  • Both LEDs Off: VIN very low/high-temperature shutdown
• Protection Features: Input overcurrent, under-voltage, over-temperature, short circuit, battery temperature monitoring, reverse battery protection
• Mode Setting: Onboard solder jumper for 1S/2S mode
• External LED: Option for external bicolor LED

Pin Description:

• VCC: Input voltage (5V-15V DC)
• GND: Ground
• BAT+: Battery positive terminal
• BAT-: Battery negative terminal
• STAT1: Status LED 1 (charging indicator)
• STAT2: Status LED 2 (full charge/no battery indicator)

Usage Tips:

1. Connection: Connect the input voltage to the VCC and GND pins, and the battery to the BAT+ and BAT- terminals.
2. Mode Selection: Use the onboard solder jumper to select the appropriate mode (1S for single-cell, 2S for dual-cell).
3. LED Indicators: Monitor the charging status through the onboard LEDs (red and blue) or connect an external bicolor LED for more convenient status indication.
4. Safety Precautions: Ensure proper ventilation and heat dissipation during charging to prevent overheating.
5. Protection Features: The module’s built-in protections will safeguard the battery and the module itself from various potential issues.

Package Includes:

• 1 x TP5100 8.4V/4.2V Li-ion Battery Charging Module
