MCT8316ZT-Q1 40-Pin VQFN With Exposed Thermal Pad Top View Table 6-1. Pin Functions PIN 40-pin Package TYPE(1) DESCRIPTION NAME MCT8316ZR- Q1 MCT8316ZT-Q1 ADVANCE — 35 I Advance angle level setting. This pin is a 7-level input pin set by an external resistor. AGND 2, 26 2, 26 GND Device analog ground. Refer Layout Guidelines for connections recommendation. AVDD 25 25 PWR O 3.3-V internal regulator output. Connect an X5R or X7R, 1-µF, 6.3-V ceramic capacitor between the AVDD and AGND pins. This regulator can source up to 30 mA externally. BRAKE 38 38 I High → Brake the motor when High by turning all low side MOSFETs ON Low → normal operation CP 8 8 PWR O Charge pump output. Connect a X5R or X7R, 1-µF, 16-V ceramic capacitor between the CP and VM pins. CPH 7 7 PWR Charge pump switching node. Connect a X5R or X7R, 47-nF, ceramic capacitor between the CPH and CPL pins. TI recommends a capacitor voltage rating at least twice the normal operating voltage of the device. CPL 6 6 PWR DIR — 36 I Direction pin for setting the direction of the motor rotation to clockwise or counterclockwise. DRVOFF 21 21 I When this pin is pulled high the six MOSFETs in the power stage are turned OFF making all outputs Hi-Z. FB_BK 3 3 PWR I Feedback for buck regulator. Connect to buck regulator output after the inductor/resistor. FGOUT 40 40 O Motor Speed indicator output. Open-drain output requires an external pull-up resistor to 1.8V to 5.0V. It can be set to different division factor of Hall signals (see FGOUT Signal) MCT8316Z-Q1 SLVSGO3 – DECEMBER 2021 www.ti.com 4 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: MCT8316Z-Q1 |
