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. ## Claims ### Claim 1 A method, comprising: receiving, by a first device in a stack, a command from a controller, wherein the stack includes of devices; and 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. ### Claim 2 (depends on 1) The method of claim 1, wherein the first device is an end device in the stack located farther from the controller than another device in the stack, and wherein the amount of power is a first amount of power, the method including dissipating, by the end device, a second amount of power responsive to a forwarding time for the command. ### Claim 3 (depends on 1) The method of claim 1, wherein the amount of power is a first amount of power responsive to a value of a first register, and wherein the device response time is a first device response time, the method including: receiving, by a second device in the stack, the command from the controller; and dissipating, by the second device, a second amount of power responsive to a difference between: the longest response time; and a second device response time for the second device to respond to the command; wherein the second amount of power is responsive to a value of a second register. ### Claim 4 (depends on 1) The method of claim 1, wherein the first device is an end device in the stack located nearer to the controller than another device in the stack, and wherein the amount of power is a first amount of power responsive to a value of a first register, the method including dissipating, by the first device, a second amount of power while responding to the command, wherein the second amount of power is responsive to a value of a second register. ### Claim 5 (depends on 1) The method of claim 1, wherein dissipating the amount of power includes providing an amount of current to an internal load of the first device. ### Claim 6 (depends on 1) The method of claim 1, wherein dissipating the amount of power includes providing, by the first device, a signal to a communication interface. ### Claim 7 (depends on 1) The method of claim 1, wherein an amount of power dissipated by each of the devices responsive to the command is approximately equal. ### Claim 8 A device of a stack that includes multiple 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 dissipate 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 device to respond to the command. ### Claim 9 (depends on 8) The device of claim 8, wherein: the device is an end device in the stack located farther from the controller than another device in the stack; the amount of power is a first amount of power; and the processor is configured to cause the device to dissipate a second amount of power responsive to a forwarding time for the command. ### Claim 10 (depends on 8) The device of claim 8, including a first register, wherein the amount of power is programmable responsive to a value of the first register. ### Claim 11 (depends on 8) The device of claim 8, including a first register and a second register, wherein: the device is an end device in the stack located nearer to the controller than another device in the stack; the amount of power is a first amount of power responsive to a value of the first register; the processor is configured to cause the device to dissipate a second amount of power while responding to the command; and the second amount of power is responsive to a value of the second register. ### Claim 12 (depends on 8) The device of claim 8, including an internal load, wherein the processor being configured to cause the device to dissipate the amount of power includes the processor being configured to cause the device to provide an amount of current to the internal load. ### Claim 13 (depends on 8) The device of claim 8, wherein the processor being configured to cause the device to dissipate the amount of power includes the processor being configured to provide a signal to the communication interface. ### Claim 14 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 and a second battery monitor; wherein the first and second battery monitors are configured to receive a command from the battery management controller; and wherein the first battery monitor is configured to dissipate an amount of power responsive to a difference between: a longest response time for the first and second battery monitors to respond to the command; and a device response time for the first battery monitor to respond to the command. ### Claim 15 (depends on 14) The system of claim 14, wherein: the first battery monitor is an end device in the stack located farther from the battery management controller than another device in the stack;
