4 / 24 page 4 DS786A1 CS4412A RAMP_CAP 24 Output Ramp Capacitor (Input) - Used by the PWM PopGuard Transient Control to suppress the initial pop in half-bridge-configured outputs. GND 10,13 14,15 16,17 18,19 20,47 48 Ground (Input) - Ground for the internal logic and I/O. These pins should be connected to the common system ground. VP 25,30 31,36 High Voltage Output Power (Input) - High voltage power supply for the individual output power half-bridge devices. PGND 22,23 27,28 33,34 37,38 39,40 Power Ground (Input) - Ground for the individual output power half-bridge devices. These pins should be connected to the common system ground. OUT4 OUT3 OUT2 OUT1 26 29 32 35 PWM Output (Output) - Amplified PWM power outputs. TWR 41 Thermal Warning Output (Output) - Thermal warning output. Open drain, active low. See “Device Protection and Error Reporting” on page 19. ERRUVTE 42 Thermal and Under-voltage Error Output (Output) - Error flag for thermal shutdown and under- voltage. Open drain, active low. See “Device Protection and Error Reporting” on page 19 ERROC12 ERROC34 43 44 Over-current Error Output (Output) - Over-current error flag for the associated outputs. Open drain, active low. See “Device Protection and Error Reporting” on page 19. RAMP 45 Ramp-up/down Select (Input) - Set high to enable ramping. When set low, ramping is disabled. See “PWM Popguard Transient Control” on page 13. Thermal Pad - Thermal Pad - Thermal relief pad for optimized heat dissipation. See “QFN Thermal Pad” on page 20 for more information.
