DW01A Li-ion Battery Protection IC: Internal Diagram and Working
Learn how the DW01A IC protects lithium ion batteries from overcharge and over discharge by detecting and controlling voltage.
00:00:00 Learn how the DW01A IC protects lithium ion batteries from overcharge and over discharge. Discover how it detects and controls voltage to ensure safe operation.
🔋 The DW01A IC is used to protect lithium-ion batteries from overcharge and overdischarge.
⚡ When the voltage of the battery reaches 4.2 volts, the IC switches off the charging mode to prevent overcharging.
❌ When the charging mode is switched off, no current flows through the circuit, preventing overcharging.
00:01:06 The video explains the internal diagram and working of the DW01A Li-ion battery protection IC. It protects against overvoltage and overdischarge.
⚡️ The Li-ion battery protection IC prevents overcharging by comparing the voltage with a reference voltage and cutting off the charging when it exceeds 4.2 volts.
🔋 Additionally, the IC protects against over-discharging by detecting when the battery voltage falls below 2.4 volts and disabling the discharge path.
00:02:10 The video explains the internal diagram and working of the DW01A Li-ion Battery Protection IC.
💡 The Li-ion battery protection IC uses an over discharge MOSFET to prevent current flow when the voltage drops below a certain threshold.
⚙️ The IC has a current sensing pin that measures and compares the current flow to ensure safe operation.
🔋 The battery can only be used when its voltage is above three volts, requiring it to be charged before discharging.
00:03:15 This video discusses the internal diagram and working of the DW01A Li ion Battery Protection IC. It provides over current, short circuit, over voltage, and under voltage protection for the battery.
💡 The DW01 IC acts as a protection mechanism for Li-ion batteries.
🔋 It prevents overvoltage (above 4.2 volts) and undervoltage (below 2.4 volts) conditions.
⚡️ The IC also offers protection against overcurrent and short circuits.
00:04:18 This video explains the internal diagram and working of the DW01A Li-ion Battery Protection IC, which provides protection against overcharge, overdischarge, and short circuits.
The DW01A Li-ion Battery Protection IC cuts off the charging section when the battery voltage exceeds 4.2 volts.
The DW01A IC turns on the charging section again when the battery discharges to 4.1 volts.
The TP4056 is used in combination with the DW01A IC to provide constant current, constant voltage, and protection against overvoltage, short circuit, and overdischarge.
