PRODUCTION DATA
| PIN | I/O(1) | DESCRIPTION | |||
|---|---|---|---|---|---|
| NUMBER | NAME | ||||
| 4–5 | BOOT | I | Input voltage supply of the high-side linear regulator. The external bootstrap capacitor is placed between BOOT and ASW. The cathode of the external bootstrap diode is connected to this pin. A Zener diode clamp may be needed between BOOT and ASW in order to not exceed the absolute maximum electrical rating. | ||
| 6, 9–12 | ASW | — | High-side driver signal return. ASW(6) is internally connected to PSW and the high-side thermal pad. Connect ASW(9-12) to ASW externally. | ||
| 13–14 | BST | O | For bootstrap charging that utilizes the internal bootstrap switch, this pin serves as the bootstrap diode anode connection point. The external high-side bootstrap capacitor can be charged through this pin using the input voltage applied to VIN, internal bootstrap switch, and external bootstrap diode(s). | ||
| 15 | BP7L | O | Low-side 7-V linear regulator output. A minimum of 1-uF capacitance is required from BP7L to AGND. | ||
| 16–17 | VIN | I | Gate driver input voltage supply. Input voltage range is from 10 V to 14 V. This pin serves as the input to the low-side linear regulators and the internal bootstrap switch. For bootstrap charging directly from the input voltage, VIN also serves as the bootstrap diode anode connection point. | ||
| 18, 24 | AGND | — | Low-side driver signal return. AGND(24) is internally connected to PGND and the low-side thermal pad. Connect AGND(18) to AGND externally. | ||
| 19 | DHL | I | High-side to low-side dead time set. In PWM mode, a resistor from DHL to AGND sets the dead time between the high-side turn-off and low-side turn-on. In independent input mode (IIM), DHL is used to configure the input interlock protection of the driver. DHL is connected to BP5L in IIM with interlock enabled. A resistor valued between 100 kΩ and 220 kΩ is connected from DHL to AGND for IIM with interlock disabled. | ||
| 20 | DLH | I | Low-side to high-side dead time set. In PWM mode, a resistor from DLH to AGND sets the dead time between the low-side turn-off and high-side turn-on. In independent input mode (IIM), DLH is used to configure the input interlock protection of the driver. A resistor valued between 100 kΩ and 220 kΩ is connected from DLH to AGND for IIM with interlock enabled. DLH is connected to BP5L in IIM with interlock disabled. | ||
| 21 | PGOOD | O | Power good pin. Asserts low when any of the low-side internal linear regulators or VIN goes into undervoltage lockout. Requires a 10-kΩ pull-up resistor to BP5L. | ||
| 22 | EN_HI | I | Enable input or high-side driver control input. In PWM mode this is used as an enable pin. In independent input mode (IIM) this serves as the control input for the high-side driver. | ||
| 23 | PWM_LI | I | PWM input or low-side driver control input. In PWM mode this is used as the PWM input to the gate driver. In independent input mode (IIM) this serves as the control input for the low-side driver. | ||
| 25–27 | PGND | — | Low-side power ground. Connect to the source of the low-side GaN FET. Internally connected to AGND and low-side thermal pad. Connect to AGND at printed circuit board level. | ||
| 28–30 | BP5L | O | Low-side 5-V linear regulator output. A minimum of 1-μF capacitance is required from BP5L to PGND. | ||
| 31–33 | LOH | O | Low-side driver source current ouput. Connect to the gate of low-side GaN FET with short, low inductance path. A resistor between LOH and the gate of the GaN FET can be used to adjust the turn-on speed. | ||
| 34–36 | LOL | O | Low-side driver sink current output. Connect to the gate of the low-side GaN FET with short, low inductance path. A resistor between LOL and the gate of the GaN FET can be used to adjust the turn-off speed. | ||
| 37–39 | PSW | — | Switch node connection. Connect to the source of the high-side GaN FET. Internally connected to ASW and high-side thermal pad. Connect to ASW at printed circuit board level. | ||
| 40–42 | BP5H | O | High-side 5-V linear regulator output. A minimum of 1-μF capacitance is required from BP5H to PSW. | ||
| 43–45 | HOH | O | High-side driver source current output. Connect to the gate of the high-side GaN FET with short, low inductance path. A resistor between HOH and the gate of the GaN FET can be used to adjust the turn-on speed. | ||
| 46–48 | HOL | O | High-side driver sink current output. Connect to the gate of the high-side GaN FET with short, low inductance path. A resistor between HOL and the gate of the GaN FET can be used to adjust the turn-off speed. | ||
| 1–3, 7–8 | NC | — | No connect. These pins are not connected internally. They can be left unconnected or connected to the high-side reference voltage (ASW) in order to avoid floating metal and prevent charge buildup. | ||
| — | PSW PAD | — | High-side thermal pad. Internally connected to ASW(6) and PSW. Connect to SW pins. | ||
| — | PGND PAD | — | Low-side thermal pad. Internally connected to AGND(18) and PGND. Connect to GND pins. | ||
