Hi9100
Hichips(智芯) · DC-DC Converters · SOT-23-5
Hi9100 from Hichips(智芯), in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DRV | output | Drives the gate of the external power MOSFET, with pull-up current of 400 mA and pull-down current of 600 mA (typ.) per the electrical characteristics. |
| 2 | GND | power_in | Chip ground; per the PCB guidance, it should be tied at a single point together with the VDD capacitor ground and the CS sense-resistor ground. |
| 3 | CS | input | Current-sense input for peak-current limiting and setting the maximum output current via a resistor to GND, with a 200 mV reference (VCS limit 400 mV max) and a CS pin rating of -0.3 to 40 V. |
| 4 | FB | input | Output-voltage sense input connected to the resistor divider, with a typical 1.16 V reference (1.125-1.195 V) and an absolute maximum rating of -0.3 to 6 V. |
| 5 | VDD | power_in | Supply input that starts operation above 6.5 V, with UVLO at 3.5 V, an internal clamp of 24 V max (absolute maximum -0.3 to 40 V), and a bypass capacitor of at least 10 uF required. |
