4 / 26 page  SMS66 Preliminary Information Summit Microelectronics, Inc 2070 1.0 7/16/03 4 Pin Number Pin Type Pin Name Pin Description 1 DATA SDA I 2C Bi-directional data line 2 CLK SCL I 2C Clock line 3 IN A2 The address pin is biased either to VDD_CAP or GND. When communicating with the SMS66 over the 2-wire bus A2 provides a mechanism for assigning a unique bus address. 4 IN MR Programmable active high/low input. When asserted the RST output will be go active. When de-asserted the RST output will go inactive immediately after a reset timeout period (tPRTO) if there are no RST trigger sources active. This timeout period makes it suitable to use a pushbutton for manual reset. 5 IN PWR_ON/OFF Programmable active high/low input signals the start of the power sequencing. When asserted the part will sequence the supplies on and when de-asserted the part will sequence the supplies off. 6 IN FS Programmable active high/low input. Force shutdown is used to immediately turn off all converter enable signals (PUP outputs) 7 OUT FAULT Programmable active high/low open drain Fault output. Active when a programmed fault condition exists on AIN1, AIN2, or the internal temperature sensor. 8 OUT HEALTHY Programmable active high/low open drain Healthy output. Active when all programmed power supply inputs and monitored inputs are within OV and UV limits. 9 OUT RST Programmable active high/low open drain Reset output. Active when a programmed fault condition exists on any power supply inputs or monitored inputs or when MR is active. RST has a programmable timeout period with options for 0.64ms, 25ms, 100ms and 200ms. 10 IN AIN1 General purpose monitored analog input 11 IN AIN2 General purpose monitored analog input 12, 44, 39, 34, 29, 24, 19 GND GND Ground 13 IN VREF_ADC Voltage reference input used for A/D conversion where: (4XVREF_ADC) = Full Scale for VMA-F and VDD (12XVREF_ADC) = FS for 12VIN (2XVREF_ADC) = FS for AIN1 and AIN2. VREF_ADC can be connected to VREF_CNTL in most applications. 14 O VREF_OUT Voltage reference output for the internal 1.25V reference. 41,36, 31,26, 21,16 IN VMX Monitored voltage input, VMA through VMF PIN DESCRIPTIONS |
