TERMINAL FUNCTIONS (UCC27523 / UCC27524 / UCC27525) TERMINAL I/O FUNCTION NUMBER NAME 1 ENA I Enable input for Channel A: ENA biased LOW Disables Channel A output regardless of INA state, ENA biased HIGH or floating Enables Channel A output, ENA allowed to float hence the pin-to-pin compatibility with UCC2732X N/C pin. 2 INA I Input to Channel A: Inverting Input in UCC27523, Non-Inverting Input in UCC27524, Inverting Input in UCC27525, OUTA held LOW if INA is unbiased or floating. 3 GND - Ground: All signals referenced to this pin. 4 INB I Input to Channel B: Inverting Input in UCC27523, Non-Inverting Input in UCC27524, Non-Inverting Input in UCC27525, OUTB held LOW if INB is unbiased or floating. 5 OUTB O Output of Channel B 6 VDD I Bias supply input 7 OUTA O Output of Channel A 8 ENB I Enable input for Channel B: ENB biased LOW Disables Channel B output regardless of INB state, ENB biased HIGH or floating Enables Channel B output, ENB allowed to float hence the pin-to-pin compatibility with UCC2732X N/C pin. TERMINAL FUNCTIONS (UCC27526) TERMINAL I/O FUNCTION NUMBER NAME 1 INA- I Inverting Input to Channel A: When Channel A is used in Non-Inverting configuration, connect INA- to GND in order to Enable Channel A output, OUTA held LOW if INA- is unbiased or floating. 2 INB- I Inverting Input to Channel B: When Channel B is used in Non-Inverting configuration, connect INB- to GND in order to Enable Channel B output, OUTB held LOW if INB- is unbiased or floating. 3 GND - Ground: All signals referenced to this pin. 4 OUTB I Output of Channel B 5 VDD O Bias Supply Input 6 OUTA I Output of Channel A 7 INB+ O Non-Inverting Input to Channel B: When Channel B is used in Inverting configuration, connect INB+ to VDD in order to Enable Channel B output, OUTB held LOW if INB+ is unbiased or floating. 8 INA+ I Non-Inverting Input to Channel A: When Channel A is used in Inverting configuration, connect INA+ to VDD in order to Enable Channel A output, OUTA held LOW if INA+ is unbiased or floating.
