Texas Instruments EMB1433Q
The EMB1433Q is a protection chip that provides an additional layer of safety to the regular battery stack voltage acquisition chain. The EMB1433Q device can monitor a stack of 6 to 14 cells, with a maximum of 60 V at the top of the stack and can support a multimodule battery pack architecture. The high and low window thresholds (HTH, LTH) and the auxiliary threshold (AUXTH) are set through external resistor dividers.| Part No. | EMB1433Q |

DESCRIPTION
Device functions are independent from the main acquisition path, providing a layer of redundancy to the battery system. An internal flag signal is asserted any time that either one or more cells of the stack are outside a “safety” voltage window (undervoltage, overvoltage) or the voltage on the positive pin of the external thermistor connected to the pin AUX exceeds a customer selectable threshold (AUXTH).
