TDA1562Q Datasheet PDF - NXP

●GENERAL DESCRIPTION

●The TDA1562 is a monolithic integrated 70 W/4 Ω Bridge-Tied Load (BTL) class-H high efficiency power amplifier in a 17 lead DIL-bent-SIL plastic power package.

●The device can be used for car audio systems (e.g. car radios and boosters) as well as mains fed applications (e.g. midi/mini audio combinations and TV sound).

●FEATURES

●• Very high output power, operating from a single low supply voltage

●• Low power dissipation, when used for music signals

●• Switches to low output power at too high case temperatures

●• Few external components

●• Fixed gain

●• Differential inputs with high common mode rejection

●• Mode select pin (on, mute and standby)

●• Status I/O pin (class-H, class-B and fast mute)

●• All switching levels with hysteresis

●• Diagnostic pin with information about:

●   – Dynamic Distortion Detector (DDD)

●   – Any short-circuit at outputs

●   – Open load detector

●   – Temperature protection.

●• No switch-on or switch-off plops

●• Fast mute on supply voltage drops

●• Quick start option (e.g. car-telephony/navigation)

●• Low (delta) offset voltage at the outputs

●• Load dump protection

●• Short-circuit safe to ground, supply voltage and across the load

●• Low power dissipation in any short-circuit condition

●• Protected against electrostatic discharge

●• Thermally protected

●• Flexible leads.
