Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this data sheet is not implied. Exposure of the device to the absolute maximum ratings for an extended period may degrade the device and affect its reliability. nF Note 1: 4 layer PCB Pin Description Pin No. Pin Name 1 G2 2 A2 3 NC 4 G4 5 NC 6 INB 7 INA 8 VDD 9 VPP 10 NC 11 G3 12 NC 13 A1 14 G1 15 NC 16 GND Description High Side Gate Driver 2 Output High Side Gate Driver 2 Floating DC Power Return No Connect Low Side Gate Driver 4 Output No Connect Control Input for High Side Driver 2 and Low Side Driver 3 Control Input for High Side Driver 1 and Low Side Driver 4 Logic Power Supply High Voltage Negative Lamp Supply No Connect Low Side Gate Driver 3 Output No Connect High Side Gate Driver 1 Floating DC Power Return High Side Gate Driver 1 Output No Connect Ground NOTE: The Exposed Thermal Pad of the device package must be connected to Ground. ESD Warning ESD (electrostatic discharge) sensitive device. Although the MX6895 features proprietary ESD protection circuitry, permanent damage may be sustained if subjected to high energy electrostatic discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
