5 / 16 page 1999 Aug 30 5 Philips Semiconductors Product specification Dual BTL power driver TDA7073A; TDA7073AT LIMITING VALUES In accordance with the Absolute Maximum System (IEC 134). Note 1. The outputs can be short-circuited over the load, to the supply and to ground at all input conditions. THERMAL CHARACTERISTICS Notes 1. TDA7073A: VP = 5 V; RL =8 Ω; The typical voltage swing = 5.8 V and Vloss is 2.1 V therefore IO = 0.36 A and Ptot =2 × 0.76 W = 1.52 W; Tamb (max) = 150 − 1.52 × 50 = 74 °C. 2. TDA7073AT: VP = 5 V; RL =16 Ω; typical voltage swing = 5.8 V and Vloss is 2.1 V therefore IO = 0.18 A and Ptot =2 × 0.38 W = 0.76 W; Tamb (max) = 150 − 0.76 × 95 = 77 °C. SYMBOL PARAMETER CONDITIONS MIN. MAX. UNIT VP positive supply voltage range − 18 V IORM repetitive peak output current − 1A IOSM non repetitive peak output current − 1.5 A Ptot total power dissipation TDA7073A Tamb <25 °C − 2.5 W TDA7073AT Tamb <25 °C − 1.32 W Tstg storage temperature range −55 +150 °C Tvj virtual junction temperature − 150 °C Tsc short-circuit time see note 1 − 1hr SYMBOL PARAMETER CONDITIONS VALUE UNIT Rth (j-a) from junction to ambient TDA7073A in free air; note 1 50 K/W TDA7073AT in free air; note 2 95 K/W |
