Abstract
A method includes receiving, by a first device in a stack, a command from a controller. The stack includes multiple devices. The method also includes dissipating, by the first device, an amount of power responsive to a difference between a longest response time for the devices to respond to the command, and a device response time for the first device to respond to the command.
Claims18
A method, comprising:
- receiving, by a plurality of daisy chained devices in a stack, a command from a controller;
- responding to the command, by each of the plurality of daisy chained devices in the stack, in respective response times, wherein a first device responds in a first response time;
- dissipating, by the first device, a first amount of power responsive to the first response time;
- and
- dissipating, by the first device, a second an amount of power responsive to a difference between:
- a longest response time of the respective response times, wherein the longest response time is greater than the first response time;
- and
- the first response time.
5 more elements
A device of a stack that includes multiple daisy chained devices, the device comprising:
- a communication interface configured to receive a command from a controller;
- and
- a processor coupled to the communication interface, the processor configured to cause the device to:
- respond to the command in a first response time;
- dissipate a first amount of power responsive to the first response time;
- dissipate a second amount of power responsive to a difference between:
- a longest response time of the daisy chained devices to respond respectively to the command;
- and
- the first response time.
6 more elements
A system, comprising:
- a battery management controller;
- and
- a stack of battery monitors coupled to the battery management controller, wherein the stack includes a first battery monitor daisy chained to a second battery monitor;
- wherein the first and second battery monitors are configured to receive a command from the battery management controller;
- wherein the first battery monitor is configured to dissipate a first amount of power;
- wherein the second battery monitor is configured to dissipate a second amount of power;
- and
- wherein the first battery monitor is configured to dissipate the first amount of power responsive to a first response time and responsive to a difference between:
- a longest response time for the first and second battery monitors to respond to the command;
- and
- the first response time.
