Power management integrated circuits (power management ICs or PMICs or PMU as unit) are integrated circuits for power management. A power management integrated circuit (PMIC) is used to manage power on an electronic devices or in modules on devices that may have a range of voltages. Power management ICs are solid state devices that control the flow and direction of electrical power. A PMIC may include battery management, voltage regulation, and charging functions. Although PMIC refers to a wide range of chips (or modules in system-on-a-chip devices), most include several DC/DC converters or their control part. PMICs are frequently used to power small, battery-operated devices since the integration of multiple functions into a single chip results in more efficient use of space and system power. Functions commonly integrated into a PMIC include voltage converters and regulators, Battery Mangement ICs, battery fuel gauges, LDOs, Mosfets, IGBT, LED drivers, real-time clocks, power sequencers, and power control.

Hi dear,
A scan counter is provided to allow confirmation of receipt of the Scan and Measure commands. This is a 4-bit counter located in the Scan Count register (page 1, address 6’h16). The counter increments each time a Scan or Measure command is received. This allows the host microcontroller to compare the counter value before and after the Scan or Measure command was sent to verify receipt. The counter wraps to zero when overflowed. The scan counter increments whenever the ISL94212 receives a Scan or Measure command. The ISL94212 does not perform a requested scan or measure function if there is already a scan or measure function in progress, but it still increments the scan counter.
Thanks

The -00 will change as the OTP changes.
If -A is included this mean the part is automotive qualified.
if -AT this means the part is automotive qualified and has gone through high temperture testing.
If -A or -AT is not present, then the part is consumer/industrial grade. The functionalty is the same.

Bidirectional chargers can be used for two different applications. The first and most talked about is Vehicle-to-grid or V2G, designed to send or export energy into the electricity grid when the demand is high. If thousands of vehicles with V2G technology are plugged in and enabled, this has the potential to transform the way in which electricity is stored and generated. EVs have large, powerful batteries, so the combined power of thousands of vehicles with V2G could be enormous.
Vehicle-to-grid or V2G – exports energy to support the electricity grid.
Vehicle-to-home or V2H – energy is used to power a home or business.
The second use of bidirectional chargers is for Vehicle-to-home or V2H. As the names suggest, V2H enables an EV to be used much like a home battery system to store excess solar energy and power your home.
Vehicle-to-grid is where a portion of the EV battery energy is discharged and exported to the electricity grid when the demand is high in exchange for an incentive or reduced electricity costs, depending on the service contract. To participate in V2G programs, you will require a bidirectional DC charger and a compatible EV.
Vehicle-to-home or V2H is similar to the V2G, but the energy is used locally to power a home instead of being fed into the electricity grid. This enables the EV to function much like a regular household battery system to help increase self-sufficiency, especially when combined with rooftop solar. Another benefit of V2H is the ability to provide backup power in the event of a blackout.

I have a 8S4P LiFePO4 pack being controlled by the ISL94202 but our BMS board doesn’t use a MCU so it’s dependent on the 94202 chip. Currently we have a LED controlled by the /SD line. If there’s an error the LED lights and let’s the end user know something is wrong.
The issue is why does the /SD line go active when the unit goes into SLEEP mode? We need the chip go go into a low current state to keep the battery from going low when the unit isn’t being used. But since the /SD line is active during SLEEP mode we can’t use that to control the error LED.
Is there any way to be able to indicate to the end user that an error has occurred but not during SLEEP mode?

If either pin is used to drive an external circuit care must be taken to prevent complete discharge of the cells.
