MAX16125Dual Pushbutton Controllers in Tiny 6-Bump WLP Package | Evaluation Boards | 5 | Active | The MAX16122–MAX16125 pushbutton controllers with single-supply monitors monitor one or two pushbuttons and generate a hard reset signal if the buttons are pushed and held for a setup delay. The devices make it easy to "hide" the hard reset function in an existing pushbutton, such as a soft power switch. These devices operate from 1.6V to 5.5V and consume a quiescent current of only 5µA at 3V.The MAX16122–MAX16125 have pin programmable or resistor-adjustable setup delay. Connect the SEL pin to GND, VCC, or leave it unconnected to select the different setup delays (depending on part suffix, see Table 1a in the full data sheet) or connect an external resistor from SEL to GND to set the setup delays (E suffix only, see Table 1b in the full data sheet).The MAX16124/MAX16125 have one manual reset input (active-low MR), a reset output (active-low RESET), and a soft reset output (active-low SRESET) which mirrors the state of the input. The MAX16122/MAX16123 have two identical manual reset inputs (active-low MR1 and active-low MR2) and one reset output (active-low RESET). A deglitch block is connected to each input to add a delay to the falling edge with a fixed deglitch period of 20ms (tDB).The devices feature a comparator that monitors the input supply voltage. A variety of factory-trimmed threshold options accommodate different supply voltages and tolerances, eliminating external components. The factory-set reset thresholds range from 1.58V to 4.63V to monitor 5V, 3.3V, 2.5V, and 1.8V supplies.The MAX16122–MAX16125 are offered in a tiny 0.86mm x 1.25mm, 6-bump WLP package and are specified over the automotive temperature range (-40°C to +125°C).ApplicationsEbook ReadersGlucose Monitors/Patient MonitorsPortable InstrumentationPortable/Battery-Powered EquipmentSmartphonesTablet PCs |
MAX16126Load-Dump/Reverse-Voltage Protection Circuits | DC DC Switching Controllers | 18 | Active | The MAX16126/MAX16127 load-dump/reverse-voltage protection circuits protect power supplies from damaging input voltage conditions, including overvoltage, reverse-voltage, and high-voltage transient pulses. Using a built-in charge pump, the devices control two external back-to-back n-channel MOSFETs that turn off and isolate downstream power supplies during damaging input conditions, such as an automotive load-dump pulse or a reverse-battery condition. Operation is guaranteed down to 3V to ensure proper operation during automotive cold-crank conditions. These devices feature a flag output (active-low FLAG) that asserts during fault conditions.For reverse-voltage protection, external back-to-back MOSFETs outperform the traditional reverse-battery diode, minimizing the voltage drop and power dissipation during normal operation.The MAX16126/MAX16127 use external resistors to adjust the overvoltage and undervoltage comparator thresholds for maximum flexibility.The MAX16127 provides limiter-mode fault management for overvoltage and thermal shutdown conditions; whereas the MAX16126 provides switch-mode fault management for overvoltage and thermal shutdown conditions. In the limiter mode, the output voltage is limited and active-low FLAG is asserted low during a fault. In the switch mode, the external MOSFETs are switched off and active-low FLAG is asserted low after a fault. The switch mode is available in four options: latch mode, 1 autoretry mode, 3 autoretry mode, and always autoretry mode.The MAX16126/MAX16127 are available in 12-pin TQFN packages. These devices operate over the automotive temperature range (-40°C to +125°C).ApplicationsAutomotiveAvionicsIndustrialTelecom/Server/Networking |
