TEA1791AT

NXP Semicon · AC-DC Controllers & Regulators · SO-8

TEA1791AT from NXP Semicon, in a SO-8. 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 SRSENSE input Synchronous timing input that activates the SR driver at −310 mV typical, regulates at −55 mV and deactivates at −12 mV, with a continuous voltage limit of 120 V.
2 GND power_in Ground reference pin; all voltages in the datasheet are measured with respect to this pin.
3 n.c. unconnected Not connected.
4 DRIVER output Driver output for the external SR MOSFET, with a typical output voltage limit of 10 V (12 V maximum) and a duty-cycle-limited current rating of −0.8 A to +3 A (duty cycle below 10 %).
5 n.c. unconnected Not connected.
6 n.c. unconnected Not connected.
7 n.c. unconnected Not connected.
8 VCC power_in Supply voltage pin; the IC leaves undervoltage lockout above 8.5 V typical and re-enters it below 8.0 V typical, with a continuous supply limit of −0.4 V to +38 V.
