TB2904HQ (o)
Maximum Power 43 W BTL × 4-ch Audio Power IC
The TB2904H (o) is 4-ch BTL audio amplifier for car audio applications.
This IC can generate higher power: POUT MAX = 43 W as it includes the pure complementary P-ch and N-ch DMOS output stage.
It is designed to yield low distortion ratio for 4-ch BTL audio power amplifier, built-in standby function, muting function, and various kinds of protectors.
Additionally, Off-set detector is built in.
Features
• High power output
: POUT MAX (1) = 43 W (typ.)
P (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω)
: POUT MAX (2) = 39 W (typ.)
(VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω)
: POUT (1) = 26 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
: POUT (2) = 23 W (typ.)
(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
• Low distortion ratio: THD = 0.015% (typ.) (VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω)
• Low noise: VNO = 90 µVrms (typ.) (VCC = 13.2 V, Rg = 0 Ω, BW = 20 Hz to 20 kHz, RL = 4 Ω)
• Built-in standby switch function (pin 4)
• Built-in muting function (pin 22)
• Built-in Off-set detection function (pin 25)
• Built-in various protection circuits: Thermal shut down, overvoltage, out to GND, out to VCC, out to out short, speaker burned
• Operating supply voltage: VCC (opr) = 9 to 18 V (RL = 4 Ω)
Note 1: Since this device’s pins have a low withstanding voltage, please handle it with care.
Note 2: Install the product correctly. Otherwise, it may result in break down, damage and/or degradation to the product or equipment.
Note 3: These protection functions are intended to avoid some output short circuits or other abnormal conditions temporarily. These protect functions do not warrant to prevent the IC from being damaged. In case of the product would be operated with exceeded guaranteed operating ranges, these protection features may not operate and some output short circuits may result in the IC being damaged.
Maximum Ratings (Ta = 25°C)
| Characteristics | Symbol | Rating | Unit |
|---|---|---|---|
| Peak supply voltage (0.2 s) | VCC (surge) | 50 | V |
| DC supply voltage | VCC (DC) | 28 | V |
| Operation supply voltage | VCC (opr) | 18 | V |
| Output current (peak) | IO (peak) | 9 | A |
| Power dissipation | PD (Note 2) | 125 | W |
| Operation temperature | Topr | −40 to 85 | °C |
| Storage temperature | Tstg | −40 to 85 | °C |
Note 2: Package thermal resistance θj-T = 1°C/W (typ.) (Ta = 25°C, with infinite heat sink)
The absolute maximum ratings of a semiconductor device are a set of specified parameter values, which must not be exceeded during operation, even for an instant. If any of these rating would be exceeded during operation, the device electrical characteristics may be irreparably altered and the reliability and lifetime of the device can no longer be guaranteed. Moreover, these operations with exceeded ratings may cause break down, damage and/or degradation to any other equipment. Applications using the device should be designed such that each maximum rating will never be exceeded in any operating conditions. Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set forth in this documents.
