11 / 20 page TAS5110A SLES079A – APRIL 2003 – REVISED MAY 2003 www.ti.com 11 ELECTRICAL CHARACTERISTICS Supply, TJ = 25°C (FS = 384 kHz, OUTPUTA and OUTPUTB not connected, DVDD = 3.3 V, PVDDA1 = 25 V, PVDDB1 = 25 V, PVDDA2 = 22 V, PVDDB2 = 22 V, 50% input duty cycle) PARAMETER TYP MAX UNIT DVDD Operating 2 mA DVDD PWDN = 0 500 µA Sl t PVDDA1 PVDDB1 Operating(1) 6.3 mA Supply current PVDDA1, PVDDB1 PWDN = 0 25 µA PVDDA2 PVDDB2 Operating 6.5 mA PVDDA2, PVDDB2 PWDN = 0 250 µA (1) 13-k Ω resistor from BIAS_A (pin 11) to DVSS and 13-kΩ resistor from BIAS_B (pin 12) to DVSS. H-Bridge Transistors, PVDDA2 = PVDDB2 = 22 V, DVDD = 3.3 V, TJ = 25°C (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Drain-to-source breakdown voltage ID = 1 mA, PWDN = 0, Hi-Z state 28 V Forward on-state resistance, low-side drivers OUTPUTA and OUTPUTB to PVSS ISINK = 2.5 A, See Notes 1, 2, and 3, PWM_AP = PWM_BP = 0, PWM_AM = PWM_BM = 1 0.2 0.24 Ω Forward on-state resistance, high-side drivers PVDDA1 to OUTPUTA, PVDDB1 to OUTPUTB ISOURCE = 2.5 A, See Notes 1, 2, and 4, PWM_AP = PWM_BP = 1, PWM_AM = PWM_BM = 0 0.2 0.24 Ω On-state resistance matching, low-side drivers 98% On-state resistance matching, high-side drivers 98% (1) Test time should be < 1 ms to minimize temperature change (2) These parameters are measured with voltage-sensing contacts separate from the current-carrying contacts. (3) ConnectPVDDA2 and PVDDB2 to a 22-V power supply with respect to PVSS. LDROUTA,LDROUTB, BOOTSTRAPA,andBOOTSTRAPBpins open. (4) Connect PVDDA2 to 22-V power supply with respect to PVSS. LDROUTA, LDROUTB, BOOTSTRAPA, and BOOTSTRAPB capacitors are connected,respectively. Clock PWM inputs to allow bootstrap capacitors to charge. 93–99% modulation must be used on PWM_AP, PWM_AM, PWM_BP, and PWM_BM inputs to prevent the activity detector from shutting down the device during this measurement. Note that FS = 384 kHz. Electrical Characteristics, Voltage Regulator, TJ = 25°C (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Output voltage (LDROUTA, LDROUTB) IO = 5 mA, PVDDA2 = PVDDB2 = 18 V to 27 V, See Note 1, DVDD = 3.3 V 14.5 15.3 16 V (1) These voltage regulators are for internal gate drive circuits only and are not to be used under any circumstances to supply current to external circuity. |
