2 / 46 page ![]() LM96063 2 3 4 5 6 7 8 9 VDD D+ D- PWM SMBDAT TACH ALERT GND 1 10 TCRIT SMBCLK LM96063 SNIS149B – NOVEMBER 2011 – REVISED MARCH 2013 www.ti.com Connection Diagram Figure 1. WSON Package See Package Number DSC0010A PIN DESCRIPTIONS Pin Name Input/Output Function and Connection Open-Drain Digital Output. Connect to system shutdown. Pin activates when Open-Drain 1 TCRIT temperature conversion value exceeds programmed limit. Several power-on-default Digital Output limit values are available. Connect to a low-noise +3.3 ± 0.3 VDC power supply, and bypass to GND with a 0.1 µF 2 VDD Power Supply Input ceramic capacitor in parallel with a 100 pF ceramic capacitor. A bulk capacitance of 10 µF needs to be in the vicinity of the LM96063's VDD pin. Connect to the anode (positive side) of the remote diode. A 100pF capacitor can be 3 D+ Analog Input connected between pins 3 and 4. Connect to the cathode (negative side) of the remote diode. A 100pF capacitor can be 4 D − Analog Input connected between pins 3 and 4. Open-Drain Open-Drain Digital Output. Connect to fan drive circuitry. The power-on default for this 5 PWM Digital Output pin is low (pin 4 pulled to ground). 6 GND Ground This is the analog and digital ground return. Open-Drain This pin is an open-drain ALERT output. 7 ALERT Digital Output Tachometer input for measuring fan speed. Note the TACH input is disabled upon 8 TACH Digital Input power-up and needs to be enabled for use by setting TCHEN bit 2 of Configuration Register 03h. Digital Input/ 9 SMBDAT Open-Drain Digital This is the bidirectional SMBus data line. Output 10 SMBCLK Digital Input Digital Input. This is the SMBus clock input. 2 Submit Documentation Feedback Copyright © 2011–2013, Texas Instruments Incorporated Product Folder Links: LM96063 |
