5 / 20 page LM4651 Pin Descriptions Pin No. Symbol Description 1 OUT 1 The reference pin of the power MOSFET output to the gate drive circuitry. 2,27 BS 1,BS2 The bootstrap pin provides extra bias to drive the upper gates, HG 1,HG2. 3HG 1 High−Gate #1 is the gate drive to a top side MOSFET in the H-Bridge. 4HG 2 High−Gate #2 is the gate drive to a top side MOSFET in the H-Bridge. 5,15 GND The ground pin for all analog circuitry. 6 +6V BYP The internally regulated positive voltage output for analog circuitry. This pin is available for internal regulator bypassing only. 7+V CC The positive supply input for the IC. 8 −6V BYP The internally regulated negative voltage output for analog circuitry. This pin is available for internal regulator bypassing only. 9F BKVO The feedback instrumentation amplifier output pin. 10 E RRIN The error amplifier inverting input pin. The input audio signal and the feedback signal are summed at this input pin. 11 E RRVO The error amplifier output pin. 12 TSD The thermal shut down input pin for the thermal shut down output of the LM4652. 13 STBY Standby function input pin. This pin is CMOS compatible. 14 FBK 1 The feedback instrumentation amplifier pin. This must be connected to the feedback filter from V O1 (pin 15 on the LM4652 ). 16 OSC The switching frequency oscillation pin. Adjusting the resistor from 15.5k Ω to 0Ω changes the switching frequency from 75kHz to 225kHz. 17 Delay The dead time setting pin. 18 SCKT Short circuit setting pin. Minimum setting is 10A. 19 FBK 2 The feedback instrumentation amplifier pin. This must be connected to the feedback filter from V O2 (pin 7 on the LM4652 ). 20,21 −V DDBYP The regulator output for digital blocks. This pin is for bypassing only. 22,23 −V EE The negative voltage supply pin for the IC. 24 START The start up capacitor input pin. This capacitor adjusts the start up time of the diagnostic sequence for the modulator. Refer to Start up Sequence and Timing in the Application Information section. 25 LG 1 Low−Gate #1 is the gate drive to a bottom side MOSFET in the H-Bridge. 26 LG 2 Low−Gate #2 is the gate drive to a bottom side MOSFET in the H-Bridge. 28 OUT 2 The reference pin of the power MOSFET output to the gate drive circuitry. www.national.com 5 |
