TEA1762T

NXP Semicon · AC-DC Controllers & Regulators · SOIC-14

TEA1762T from NXP Semicon, in a SOIC-14. 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 sensing the SR MOSFET drain voltage (driver activates at −310 mV typ, regulates at −55 mV, switches off at −12 mV; abs max +120 V, use ~1 kΩ series resistor).
2 POWERGND power_in Power ground, reference for all limiting values; ISENSE is regulated to 50 mV above this pin.
3 SENSEGND power_in Sense ground for accurate output voltage sensing, internally connected to power ground via two anti-parallel diodes; must stay within −0.4 V to +0.4 V.
4 PROTECT input General purpose protection input with 1.25 V typical threshold, usable with an NTC thermistor or Zener diode; max 5 V.
5 n.c. unconnected Not connected.
6 DRIVER output Driver output for the SR MOSFET gate, limited to 10 V typical with 250 mA typical source and 2.7 A typical sink capability.
7 OPTOPROT output Open-drain opto coupler driver output for current protection, max sink current 5 mA typical, goes to maximum sink current on over-temperature; max 38 V.
8 OPTOREG output Open-drain opto coupler driver output for voltage regulation, max sink current 5 mA typical; max 38 V.
9 VREF power_out Reference voltage output of 2.5 V typical for external circuitry, maximum output current limited to 1 mA.
10 VSENSE input Sense input for voltage control, regulated to 2.5 V above SENSEGND; max 5 V.
11 ISENSE input Sense input for current control, regulated or limited to 50 mV above POWERGND; max 5 V.
12 n.c. unconnected Not connected.
13 n.c. unconnected Not connected.
14 VCC power_in Supply voltage, operating range 8.6 V start-up to 38 V maximum, with undervoltage lock-out below 8.1 V typical.
