Designed to monitor the system supply voltage and assert an output during power-up, power-down, and brownout conditions, these devices provide excel- lent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltage from 1.8V to 3.6V. The MAX16072 has a push-pull, active-low reset output, the MAX16073 has a push-pull, active-high reset output, and the MAX16074 has an open-drain active-low reset output. The devices are designed to ignore fast tran- sients on VCC. The devices also include a manual reset input (MR). The MAX16072/MAX16073/MAX16074 are available in a 1mm x 1mm, space-saving, 4-bump, chip-scale pack- age (UCSPTM). Applications Portable/Battery-Powered Equipment Cell Phones PDAs MP3 Players Digital Cameras Features S Ultra-Low, 0.7µA Supply Current S Ultra-Small (1mm x 1mm), 4-Bump UCSP S 20µs, 8ms, 34ms, and 140ms Reset Timeout Options Available S Factory-Trimmed Reset Thresholds Available from 1.58V to 3.08V in Approximately 100mV Increments S Q 2.5% Threshold Accuracy Over Temperature S Manual Reset Input S Guaranteed Reset Valid to VCC = 1.0V S Immune to Short VCC Transient 19-5112; Rev 0; 1/10 +Denotes a lead(Pb)-free/RoHS-compliant package. Ordering Information Typical Operating Circuit Note: All devices are specified over the -40NC to +85NC operat- ing temperature range. Insert the desired suffix numbers (from Table 1) into the blanks “RS_ _D” to indicate the reset trip threshold. Insert the desired suffix number (from Table 2) into the blank ”D_+” to indicate the reset timeout. Minimum order quantity may apply. UCSP is a trademark of Maxim Integrated Products, Inc.
