11 / 80 page  DA7280-Automotive Wideband LRA/ERM Haptic Driver for Automotive Applications Datasheet Revision 1.4 01-Mar-2022 CFR0011-120-00 11 of 79 © 2022 Renesas Electronics 4 Characteristics 4.1 Absolute Maximum Ratings Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, so functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specification are not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Table 4: Absolute Maximum Ratings Parameter Description Conditions Min Max Unit VDD Haptics power supply Referenced to GND -0.3 6 V VDDIO Haptics IO supply -0.3 6 V VOUTN Haptic driver negative output -0.3 6 V VOUTP Haptic driver positive output -0.3 6 V VnIRQ Interrupt request line to host -0.3 6 V VSCL I2C clock input -0.3 6 V VSDA I2C data input/output -0.3 6 V VGPI General purpose inputs -0.3 6 V TA Operating ambient temperature -40 85 °C TJ Operating junction temperature -40 125 °C TSTG Storage temperature -65 150 °C ESDHBM ESD protection Human Body Model (HBM) All non-exposed pins 4 kV ESDCDM ESD protection Charged Device Model (CDM) 1 kV 4.2 Recommended Operating Conditions Unless otherwise noted, the parameters listed in Table 5 are valid for TA = 25°C, VDD = 3.8 V, and VDDIO = 1.8 V. Table 5: Recommended Operating Conditions Parameter Description Conditions Min Typ Max Unit VDD Haptics power supply (battery or regulated rail) 2.8 3.8 5.5 V VDDIO Haptics IO supply (Note 1) 1.35 1.8 5.5 V ZLD Load impedance 4 50 Ω CLD Capacitance to ground on OUTP and OUTN 1 nF fLRA LRA resonant frequency Frequency tracking enabled 50 300 Hz fLRA_OL LRA resonant frequency, open-loop Frequency tracking disabled 25 1000 Hz Note 1 During device operation VDDIO must be ≤ VDD if GPI_0, GPI_1, and GPI_2 are not grounded. |
