VSSOP-8 and SOIC-8 Packages see package numbers DGK0008A, D0008A Simplified Block Diagram Table 1. Pin Descriptions Pin Name Type Description Number Device power supply. Requires bypass capacitor of 10 µF in parallel with 0.1 µF and 1 VDD Power 100 pF. Place 100 pF closest to device pin. 2 D+ Analog Input/Output Positive input from the thermal diode. 3 D- Analog Input/Output Negative input from the thermal diode. 4 T_CRIT Digital Output Critical temperature output. Open-drain output requires pull-up resistor. Active low. 5 GND Ground Device ground. Over-temperature shutdown comparator output or SMBus slave address input. Defaults as an SMBus slave address input that selects one of three addresses. Can be tied to VDD, 6 OS/A0 Digital Input/Output GND, or to the middle of a resistor divider connected between VDD and GND. When programmed as an OS comparator output it is active low and open drain. 7 SMBDAT Digital Input/Output SMBus interface data pin. Open-drain output requires pull-up resistor. 8 SMBCLK Digital Input SMBus interface clock pin. 2 Submit Documentation Feedback Copyright © 2007–2013, Texas Instruments Incorporated Product Folder Links: LM95245 |
