5 / 26 page DRV8814 www.ti.com SLVSAB9E – MAY 2010 – REVISED NOVEMBER 2015 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range, unless otherwise noted. (1) MIN MAX UNIT Power supply voltage range VMx –0.3 47 V Power supply ramp rate VMx 1 V/µs Digital pin voltage range –0.5 7 V Input voltage VREF –0.3 4 V ISENSEx pin voltage(2) –0.8 0.8 V Peak motor drive output current, t < 1 μS Internally limited A Continuous motor drive output current(3) 0 2.5 A Continuous total power dissipation See Thermal Information Operating virtual junction temperature range, TJ –40 150 °C Operating ambient temperature range, TA –40 85 °C Storage temperature, TSTG –60 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) Transients of ±1 V for less than 25 ns are acceptable. (3) Power dissipation and thermal limits must be observed. 6.2 ESD Ratings VALUE UNIT Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V(ESD) Electrostatic discharge V Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±500 (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT VM Motor power supply voltage range(1) 8 45 V VREF VREF input voltage(2) 1 3.5 V IV3P3 V3P3OUT load current 0 1 mA fPWM Externally applied PWM frequency 0 100 kHz (1) All VM pins must be connected to the same supply voltage. (2) Operational at VREF between 0 V and 1 V, but accuracy is degraded. 6.4 Thermal Information DRV8814 THERMAL METRIC(1) PWP (HTSSOP) UNIT 28 PINS RθJA Junction-to-ambient thermal resistance 31.6 °C/W RθJC(top) Junction-to-case (top) thermal resistance 15.9 °C/W RθJB Junction-to-board thermal resistance 5.6 °C/W ψJT Junction-to-top characterization parameter 0.2 °C/W ψJB Junction-to-board characterization parameter 5.5 °C/W RθJC(bot) Junction-to-case (bottom) thermal resistance 1.4 °C/W (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953.
