3 / 20 page CAT1026, CAT1027 © Catalyst Semiconductor, Inc. 3 Doc. No. MD-3010 Rev. M Characteristics subject to change without notice PIN DESCRIPTION RESET/RESET ¯¯¯¯¯¯: RESET OUTPUTs (RESET CAT1026 Only) These are open drain pins and RESET ¯¯¯¯¯¯ can be used as a manual reset trigger input. By forcing a reset condition on the pin the device will initiate and maintain a reset condition. The RESET pin must be connected through a pull-down resistor, and the RESET ¯¯¯¯¯¯ pin must be connected through a pull-up resistor. SDA: SERIAL DATA ADDRESS The bidirectional serial data/address pin is used to transfer all data into and out of the device. The SDA pin is an open drain output and can be wire-ORed with other open drain or open collector outputs. SCL: SERIAL CLOCK Serial clock input. VSENSE: AUXILIARY VOLTAGE MONITOR INPUT The VSENSE input is a second voltage monitor which is compared against CAT1026 and CAT1027 internal reference voltage of 1.25V typically. Whenever the input voltage is lower than 1.25V, the open drain VLOW output will be driven low. An external resistor divider is used to set the voltage level to be sensed. Connect VSENSE to VCC if unused. VLOW: AUXILIARY VOLTAGE MONITOR OUTPUT This open drain output goes low when VSENSE is less than 1.25V and goes high when VSENSE exceeds the reference voltage. WDI (CAT1027 Only): WATCHDOG TIMER INTERRUPT Watchdog Timer Interrupt Input is used to reset the watchdog timer. If a transition from high to low or low to high does not occur every 1.6 seconds, the RESET outputs will be driven active.
