A device includes a current sensor, a first current monitor, and a second current monitor. The current sensor is to sense a current between an input node and an output node. The first current monitor is to disconnect the input node from the output node in response to the sensed current exceeding a first threshold current for a period exceeding a threshold period. The second current monitor is to disconnect the input node from the output node in response to the sensed current exceeding a second threshold current greater than the first threshold current.

Devices including two current monitors

A power monitor circuit, includes a power delivery path including an input voltage, a first resistor, and a load. The power monitor circuit further includes a comparator to measure a voltage across the first resistor. The comparator includes an inverting input to measure a voltage on a first side of the first resistor, a non-inverting input to measure a voltage on a second side of the first resistor, a threshold input to receive a threshold input voltage level, and an output to generate a trip signal when the voltage across the first resistor meets the threshold input voltage input level. The power monitor circuit further includes a sub-circuit in series with the first resistor, the sub-circuit including a second resistor coupled to a Zener diode, the sub-circuit to feed the input voltage back into the inverting input of the comparator. A third resistor connected between the first resistor and the second resistor, divides down the input voltage, and a fourth resistor is connected between the sub-circuit and the threshold input of the comparator. The fourth resistor is to set a voltage at which the trip signal is generated.

Regulating an output power of a monitored electronic device

Apparatuses, methods, systems, and arrangements facilitate the upkeep of an electronic device. In certain described implementations, one or more analyses and/or determinations may be completed with regard to one or more replaceable issues. If the replaceable issue(s) are determined to be deficient (including potentially deficient), then the electronic device may produce one or more upkeep-related items to facilitate an operator's upkeep thereof. Exemplary replaceable issues may be related to consumable item(s), maintenance items(s), ability items(s), etc. Exemplary upkeep-related items may include order-related items, reports, etc. Exemplary order-related items may include order forms, discount coupons and codes, network address and information combinations, etc. In an exemplary described printing device implementation, a printing device is capable of determining that at least one consumable item or maintenance item is at or near a point of being exhausted or worn out and providing an order-related item that refers to the exhausted/worn out item.
