4 / 18 page Tr i p ath Technol ogy, I n c. - Techni cal I n for m ati on 4 TA0103 – Rev 3.3/06.00 Pin Description Pin Function Description 1 AGND Analog Ground 2 OVERLOADB Logic output. When low, indicates that the level of the input signal has overloaded the amplifier. 3 V5 Positive 5 Volts 4 MUTE Logic input. When high, both amplifiers are muted. When low (grounded), both amplifiers are fully operational. 5, 6 IN2, IN1 Single-ended input (Channel 1 & 2) 7, 8 BBM0, BBM1 Break-before-make timing control 9, 12 GNDKELVIN1, GNDKELVIN2 Kelvin connection to speaker ground (Channel 1 & 2) 10, 11 OCR2, OCR1 Over-current threshold adjustment (Channel 1 & 2) 13, 14 OCS1L+, OCS1L- Over Current Sense resistor, Channel 1 low-side 15, 16 OCS1H-, OCS1H+ Over Current Sense resistor, Channel 1 high-side 17, 30 LO1COM, LO2COM Kelvin connection to source of low-side transistor (Channel 1 & 2) 18, 29 FDBKN1;FDBKN2 Feedback (Channel 1 & 2) 19 VN12 Voltage: +12 V from VSNEG. Refer to Application Information section. 20, 27 LO1, LO2 Low side gate drive output (Channel 1 & 2) 21, 26 HO1COM, HO2COM Kelvin connection to source of high-side transistor (Channel 1 & 2) 22, 25 HO1, HO2 High side gate drive output (Channel 1 & 2) 23 VSPOS Positive supply voltage 24 VSNEG Negative supply voltage 28 PGND Power Ground 31, 32 OCS2L-, OCS2L+ Over Current Sense resistor, Channel 2 low-side 33, 34 OCS2H-, OCS2H+ Over Current Sense resistor, Channel 2 high-side 35 HMUTE Logic output. When high, indicates that the output stages of both amplifiers are shut off and muted. 36, 37, 38 NC Not Connected - Must Be Left Floating 38 Pin Quad Package Pin-out (Top View) Figure 1 9 10 11 12 13 1415 16 1718 19 1 2 3 4 5 6 7 8 AGND OVERLOADB V5 IN2 IN1 BBM0 BBM1 MUTE 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 LO2 HO2COM HO2 V SNEG V SPOS HO1 H01COM LO1 |
