  1. Low Standby Current – As low as 55µA, preserving battery life when input power is removed. The TP4056 draws >200µA.
  2. Small Package – SOT-23-6 fits in compact wearables and earbud charging cases.
  3. Simple External Components – Only 3 resistors and 2 capacitors needed for basic operation.
  4. Automatic Recharge – When battery voltage drops below 4.05V (typical), a new charge cycle starts without user intervention.
  5. Reverse Polarity Protection (limited) – The BAT pin usually withstands -0.3V; do not rely on it heavily. Add external Schottky if battery may be inserted backwards.
