Description
Negative Input of Inductor Current Sense. A current sense resistor RCS
between VIN and CSN is needed to sense the inductor current. In normal
operation, (VIN－CSN) is between 120mV and 150mV(Typical).
Battery Voltage Feedback Input. Generally, FB pin should be connected to
an external resistor divider to monitor the battery voltage. When the voltage at
FB pin rises to 1.205V (Typical), the HM4033 enters termination mode, and
enters charge mode again if the voltage at FB pin falls below 1.155V(Typical).
The Positive Terminal of Input Supply. In addition to powering the internal
circuits, VIN pin also serves as the positive terminal of inductor current sense.
＋5V Regulator Output. Connect a 4.7uF or 10uF capacitor from VCC to
GND, the maximum output current is 5mA.
Gate Drive Output for External MOSFET. Connect to the gate of an
external N-channel MOSFET.
Ground(GND).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other
conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.
