TSM101AIDT from STMicroelectronics, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Vref | output | Voltage Reference Output: 1.24V, 10mA max. Do not short circuit. Provides the internal band-gap reference to external circuitry. |
| 2 | Csen | input | Current source enable input. The internal current source is enabled when the voltage on pin 2 is lower than 0.8V; used to offset the voltage measured on the sense resistor to modify the charge current. |
| 3 | Crref | input | Current Limitation Reference Input. Non-inverting input of the current limitation loop op-amp; typically tied to a resistor bridge that sets the current limit threshold. |
| 4 | GND | power_in | Ground / network reference. All voltages in the datasheet are given with respect to this pin. |
| 5 | Crin | input | Current Limitation Loop Input, connected to the sense resistor. Inverting input of the current limitation op-amp that senses load current. |
| 6 | OUTPUT | output | Output pin common to the voltage regulation and current limitation loops (ORed open-collector-style output). Can drive the primary-side LED of an optocoupler for isolated feedback to a PWM controller. |
| 7 | Vrin | input | Voltage Regulation Loop input. Inverting input of the voltage regulation op-amp; typically driven from a resistor divider sampling the output voltage. |
| 8 | VCC | power_in | Power supply input, 4.5V to 32V DC (absolute max 36V). Typical total supply current 2mA max at VCC=1.5V. |
