This compatible each other because it is same on PINOUT and parts, You can use as replacement any of these 3, You can see the diagram below shows
MINIMUM EXTERNAL COMPONENTS COUNT -NO BOOTSTRAP CAPACITORS -NO BOUCHEROT CELLS -INTERNALLY FIXED GAIN (26dB BTL) -ST-BY FUNCTION (CMOS COMPATIBLE)-NO AUDIBLE POP DURING ST-BY OPERATIONS-SOFT SHORT AT TURN-ON -THERMAL SHUTDOWN PROXIMITY -OUTPUT AC/DC SHORT CIRCUIT -OVERRATING CHIP TEMPERATURE WITH SOFT THERMAL LIMITER
The TDA737x is a new technology class AB audio processor amplifier able to work either is DUAL BRIDGE or QUAD SINGLE ENDED configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantee the
highest power performances with an extremely reduced component count.
To Power-up the ic must connect the ST_BY to Vs+ supply.

TDA737X Pinout detail Zip15 pin
There are (3) three selection want to use this IC- 4CH, 2CH, 2.1CH speaker output connection.
1. Quad type output
You can select the number 1- Quad Stereo. The design of the schematic diagram above is the input signal Pin number 4,5,11,12 is separated each.
The 4 Pin 1,2,14 and 15 output power is also separated from each other and the common line after the speaker is connected to ground (negative power supply).
Note: The output decoupling capacitors(C9, C10, C11, C12) could be reduced to 1000μF if the 2Ω operation is not required.
2. Double Bridge Type output.
If you want to double the power out for big speaker, Yes it can be but the output becomes 2CH output.
The Pin input must 4,5, is connected to each other and 11,12 is connected also, In this connection, the output to the speaker is no need to connect to common ground. The Pin1,2 is for 1CH speaker no need Capacitor, also the 14 and 15 pin is for the 2CH speaker.
3. Stereo/Bridge (2.1CH output)
For me this is the best selection among 3, The connection is 3CH output which delivers the better sound output, User must make a filtered 2.1 signal preamp which separates the low pass filter(bass sound) and connect to IN BRIDGE, take a look at schematic above.
TDA7379 Double-Bridge Type series without a PCB, You can double the output power by using two IC joint together to supply the load of speaker impedance, Its not adding wattage but it is stable for Low impedance like 2 Ohm load for great performance of Subwoofer 2 cone parallel. Note: You need to replace from 47uf capacitor to 100uf connected to SVR PIN #6
For Advance Circuit I already Test.. Parallel Bridge type to Double the power and can hold 2 Ohms Load, Also can sustain a 20 Hz frequency for better Bass Output. Lets Check Circuit Below.
WIDE SUPPLY VOLTAGE RANGE (6V -18V) MINIMUM EXTERNAL COMPONENTS NO SVR CAPACITOR NO BOOTSTRAP NO BOUCHEROT CELLS INTERNALLY FIXED GAIN STAND-BY MUTE FUNCTIONS SHORT CIRCUIT PROTECTION THERMAL OVERLOAD PROTECTION.
The TDA739x is not same to TDA737x but related to ClassAB 12Volts series, It is Zip11 pin and BRIDGE class-AB MONO audio power amplifier specially intended for car radio HighPower applications.
The TDA739x is high power capability together with the possibility to operate either in DIFFERENTIAL INPUT MODE or SINGLE ENDED INPUT MODE makes it suitable for boosters and high-end car radio equipment.
The exclusive fully complementary output stage and the internal fixed gain configuration drop the external component count.
The onboard clipping detector allows easy implementation of gain compression systems.
45W-65W/2ohms max, Best for Subwoofer system. To power-up, Connect the Pin4(CD) to ST-BY see the schematic info.

► The TDA7297 is a 15+15W DUAL dual bridge amplifier specially designed for TV and Portable Radio applications.
Schematic:
Unlike TDA7377-7379, The TDA7297 circuit is same even a pins# connection to PCB board.
Why I said this, I have TDA7297 damage IC in PCB board in a car audio amplifier and I tried to change the IC to TDA7379 as a replacement in the same board is result working OK, I test it already 100% working...
Only I add (1)capacitor on PIN no.6 cut it and place a 47uf capacitor then connect to ground to same PCB board of TDA7297.
See the comparison of a schematic diagram of TDA7297 and TDA733x.
Is almost the same schematic from ST.com that is why to try it and result OK until now I have this it is working well, the advantage is this I have now 35W RMS but before only 15W RMS, Try it...
The TDA7297 IC chips also will find on this two AC/DC amplifier when I Unboxing this BOSCA amplifier you can watch the video below shows..
The Shop store Online I bought this Two amplifier which have TDA7297 Chips when i Unboxing/Review.

It is a very flexible device capable to support the most demanding specifications in terms of power dissipation and battery transitions: its superior efficiency performance, coming from the internal exclusive structure, can reduce the dissipated output power up to 50% (when compared to conventional class AB solutions).
It is very difficult to make a homemade this circuit because of a diagram and the cost of these parts. But its deliver up to 150 watts max and Single-channel 1 Ω driving capability 84W undistorted power. See the features Pdf below.
The thick film circuit is beautiful in sound, small in distortion, powerful in power and excellent in sound quality. But not good in single supply like car battery because of split voltage input.

Comments
My system consists of 4 speakers 4 Ohm:
2x45W(max300W) 91dB
2x30W(max210W) 87dB
So i parallel pin to pin 2 tda7375 did i do something wrong?
Tda7377 max power = 30W RMS bridge(X2)
Tda7388 max power 45W rms x4
You get 45W x4 in in this test circuit. That I know.
Tda7379 is 11PIN which is 4amp inside
Answer: yes it a same circuit quad amplifier Class AB
