MAX160621% Accurate, Quad-/Hex-/Octal-Voltage µP Supervisors | Integrated Circuits (ICs) | 6 | Active | The MAX16060/MAX16061/MAX16062 are 1% accurate, quad-/hex-/octal-voltage µP supervisors in a small thin QFN package. These devices provide supervisory functions for complex multivoltage systems. The MAX16060 monitors four voltages, the MAX16061 monitors six voltages, and the MAX16062 monitors eight voltages.These devices offer independent outputs for each monitored voltage along with a reset output that asserts whenever any of the monitored voltages fall below their respective thresholds (down to 0.4V) or the manual reset input is asserted. The reset output remains asserted for the reset timeout after all voltages are above their respective thresholds and the manual reset input is deasserted. The minimum reset timeout is internally set to 140ms or can be adjusted with an external capacitor.All open-drain outputs have internal 30µA pullups that eliminate the need for external pullup resistors. However, each output can be driven with an external voltage up to 5.5V. Other features offered include a manual reset input, a tolerance pin for selecting 5% or 10% input thresholds, and a margin enable function for deasserting the outputs during margin testing.An additional feature is a watchdog timer that asserts active-low RESET when the watchdog timeout period (1.6s typ) is exceeded. The watchdog timer can be disabled by leaving WDI unconnected.These devices are offered in 16-, 20-, and 24-pin thin QFN packages (4mm x 4mm) and are fully specified from -40°C to +125°C.ApplicationsAutomotiveMultivoltage ASICsNetworking/Telecommunication EquipmentServersStorage Equipment |

MAX1606512-Channel/8-Channel Flash-Configurable System Managers with Nonvolatile Fault Registers | Development Boards, Kits, Programmers | 9 | Obsolete | The MAX16065/MAX16066 flash-configurable system managers monitor and sequence multiple system voltages. The MAX16065/MAX16066 can also accurately monitor (±2.5%) one current channel using a dedicated high-side current-sense amplifier. The MAX16065 manages up to twelve system voltages simultaneously, and the MAX16066 manages up to eight supply voltages. These devices integrate a selectable differential or single-ended analog-to-digital converter (ADC) and configurable outputs for sequencing power supplies. Device configuration information, including overvoltage and undervoltage limits, timing settings, and the sequencing order is stored in nonvolatile flash memory. During a fault condition, fault flags and channel voltages can be automatically stored in the nonvolatile flash memory for later read-back.The internal 1% accurate 10-bit ADC measures each input and compares the result to one overvoltage, one undervoltage, and one early warning limit that can be configured as either undervoltage or overvoltage. A fault signal asserts when a monitored voltage falls outside the set limits. Up to three independent fault output signals are configurable to assert under various fault conditions.Because the MAX16065/MAX16066 support a power-supply voltage of up to 14V, they can be powered directly from the 12V intermediate bus in many systems.The integrated sequencer provides precise control over the power-up and power-down order of up to twelve (MAX16065) or up to eight (MAX16066) power supplies. Eight outputs (EN_OUT1–EN_OUT8) are configurable with charge-pump outputs to directly drive external n-channel MOSFETs.The MAX16065/MAX16066 include eight/six programmable general-purpose inputs/outputs (GPIO_s). GPIO_s are flash configurable as dedicated fault outputs, as a watchdog input or output, or as a manual reset.The MAX16065/MAX16066 feature nonvolatile fault memory for recording information during system shutdown events. The fault logger records a failure in the internal flash and sets a lock bit protecting the stored fault data from accidental erasure. An SMBus or a JTAG serial interface configures the MAX16065/MAX16066. The MAX16065 is available in a 48-pin, 7mm x 7mm, TQFN package, and the MAX16066 is available in a 40-pin, 6mm x 6mm, TQFN package. Both devices are fully specified from -40°C to +85°C.ApplicationsNetworking EquipmentServersStorage/RAID SystemsTelecom Equipment (Base Stations, Access) |
