TPS2490DGSR from Texas Instruments, in a MSOP-10. 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 | EN | input | Device enable input. Threshold ~1.35 V rising / 1.25 V falling with ~100 mV hysteresis. Can be used as a programmable undervoltage lockout or logic control. Absolute max -0.3 to 100 V. |
| 2 | VREF | power_out | Reference voltage output (typ 4.0 V, range 3.9-4.1 V at 0 < IVREF < 1 mA). Used to set the power threshold on the PROG pin. Source current up to 2 mA (abs max). |
| 3 | PROG | input | Power-limit setting input. Operating input range 0.4 V to 4 V (may be set lower with reduced accuracy). Sets the MOSFET power-dissipation limit via a resistor divider from VREF. Absolute max -0.3 to 6 V. |
| 4 | TIMER | bidirectional | Fault timing capacitor. Charges at ~25 uA (source), discharges at ~2.5 uA (sink). Upper threshold ~4 V trips the fault; lower reset threshold ~1 V. Sets fault timer duration via external capacitor. |
| 5 | GND | power_in | Device ground reference. |
| 6 | PG | output | Power Good reporting output, open-drain. Sinks up to 10 mA (abs max), low-voltage typ 0.1 V at 2 mA. Deglitch delay ~9 ms. Threshold V(VCC-OUT) rising ~1.25 V, falling ~2.7 V. Requires external pull-up (up to 100 V). |
| 7 | OUT | input | Output voltage feedback input. Senses external MOSFET source/load voltage for power-limiting calculation (V(VCC-SENSE) - V(SENSE-OUT)) and Power Good detection. Operating range 0 to 80 V; abs max -1 to 100 V (withstands -2 V transient for <=1 ms). |
| 8 | GATE | output | Gate drive output for external high-side N-channel MOSFET. Sources typ 22 uA to charge the gate; sinks typ 125 mA (up to 250 mA) for fast turn-off. Gate output voltage above SENSE typ 12-16 V. Abs max -0.3 to 100 V. |
| 9 | SENSE | input | Current-limit sense input. Connect across the external current-sense resistor between VCC and SENSE. Current-limit trip threshold V(VCC-SENSE) typ 50 mV (power-limit inactive) or 25 mV (with power limiting). Input bias typ 7.5 uA. |
| 10 | VCC | power_in | Supply input. Operating range 9 V to 80 V. UVLO turn-on typ 8.4 V rising, turn-off typ 8.3 V falling. Supply current typ 450 uA enabled, 90 uA disabled. Abs max -0.3 to 100 V. |
