It is a Simple Reset/Power-On Reset type, meaning it holds the processor in reset during power-up and brown-out conditions until the supply stabilizes and the reset timeout expires. The reset output can be configured as either active-high, active-low, open-drain, or push-pull, giving the designer flexibility to interface with different processor reset architectures. The open-drain option requires an external pull-up resistor to the processor's supply rail. ## Reset timeout — adjustable, not fixed The reset timeout period is adjustable or selectable via an external capacitor on the TD pin. This allows the designer to tailor the delay to the processor's power-up sequence — a longer timeout for a slow-starting supply or a shorter one for a fast-ramping rail. No capacitor gives a nominal timeout; adding capacitance extends it proportionally. ## Sourcing and lifecycle It is a current-production part, which means no supply-chain pressure from obsolescence for new designs.","metaTitle":"DS1232LPS-2+T&R Simple Reset/Power-On Reset","metaDescription":"Maxim Integrated DS1232LPS-2+T&R MicroMonitor supervisor IC.

The T&R suffix indicates Tape & Reel packaging; the die and electrical specifications are identical to the DS1232LPS-2. The non-T&R version ships in tubes or cut tape. For a BOM that specifies the tube variant, the T&R version is a drop-in replacement — just account for the different packaging medium."},{"question":"How do I set the reset timeout on DS1232LPS-2+T&R?","answer":"Connect a capacitor between the TD pin and ground. With no capacitor, the timeout defaults to a nominal value. Adding capacitance increases the timeout period proportionally. The datasheet provides a capacitor-value vs. timeout table; select the capacitor that matches your processor's required reset hold time."},{"question":"What is DS1232LPS-2+T&R's listed type?","answer":"The device type is Simple Reset/Power-On Reset, meaning it monitors the supply voltage and generates a reset signal on power-up and during brown-out conditions."},{"question":"What is DS1232LPS-2+T&R's listed reset polarity?","answer":"The reset output can be configured as either active-high or active-low, and as either open-drain or push-pull.
