Product Details
The MAX16895—MAX16899 is a family of small, low power, voltage-monitoring circuits with sequencing capability. These miniature devices offer tremendous flexibility with an adjustable threshold capable of monitoring down to 0.5V and an external capacitor-adjustable time delay. These devices are ideal for use in power-supply sequencing, reset sequencing, and power-switching applications. Multiple devices can be cascaded for complex sequencing applications.
A high-impedance input with a 0.5V threshold allows an external resistive divider to set the monitored threshold. The output asserts (OUT = high or active-low OUT) when the input voltage rises above the 0.5V threshold and the enable input is asserted (ENABLE = high or active-low ENABLE = low). When the voltage at the input falls below 0.5V or when the enable input is deasserted (ENABLE = low or active-low ENABLE = high), the output deasserts (OUT = low or active-low OUT = high). All devices provide a capacitor-programmable delay time from when the input rises above 0.5V to when the output is asserted. The MAX1689_A versions provide the same capacitor-adjustable delay from when enable is asserted to when the output asserts. The MAX1689_P devices have a 150ns propagation delay from when enable is asserted to when the output asserts.
The MAX16895A/P offers an active-high enable input and an active-high push-pull output. The MAX16896A/P offers an active-low enable input and an active-low pushpull output. The MAX16897A/P offers an active high enable input and an active-high open-drain output. Finally, the MAX16898A/P offers an active-low enable input and an active-low open-drain output. The MAX16899A/P offers an active-low enable with an active high push-pull output.
All devices operate from a 1.5V to 5.5V supply voltage and are fully specified over the -40°C to +125°C operating temperature range. These devices are available in ultra-small 6-pin μDFN (1.0mm x 1.5mm) and thin SOT23 (1.60mm x 2.90mm) packages.
