Partnumber : TB2926HQ
Function : 45 W × 4-ch BTL Audio Power IC
Package : HZIP 25 Pin Type
Manufacturers : Toshiba
The TB2926HQ is a four-channel BTL power amplifier for car audio applications. This IC has a pure complementary P-ch and N-ch DMOS output stage, offering maximum output power (POUT MAX) of 45 W. It includes a standby switch, mute function and various protection features.
Mute Function (pin 22)
The audio mute function is enabled by setting pin 22 Low. R1 and C4 determine the time constant of the mute function. The time constant affects pop noise generated when power or the mute function is turned on or off; thus, it must be determined on a per-application basis.
1. High output power
2. POUT MAX (1) = 45 W (typ.) (VCC = 15.2 V, f = 1 kHz, JEITA max, RL = 4 Ω)
3. POUT MAX (2) = 43 W (typ.) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω)
4. POUT (1) = 26 W (typ.) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
5. POUT (2) = 23 W (typ.) (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
