Description

The TLE9015DQU is a iso UART transceiver IC.

The TLE9015DQU is a general purpose transceiver IC to be used in battery systems for enabling the

communication between the main host microcontroller and the cell supervision ICs which are usually

connected to the battery module potential. The IC is designed for Li-Ion battery packs used in hybrid electric

vehicles (HEV), plug-in hybrid electric vehicles (PHEV), battery electric vehicles (BEV) as well as stationary Li-Ion

batteries.

Additionally to the physical layer translation, the TLE9015DQU oﬀers the possibility to communicate potential

detected errors in a cell inside the battery pack to the main microcontroller.

Functional description

The transceiver IC can be powered from an external LDO via VS pin or any other source which can supply the

voltage V_VS.

To supply the communication interface, the device provides a regulated output voltage V_VDDCon pin VDDC.

The device provides a regulated output voltage V_VREGOUTwith an output current I_VREGOUTon pin VREGOUT which

can supply the GPIOs of the device or other loads.

The voltage at the VIO pin sets the logic levels and supplies the GPIOs. The pin can be connected directly to the

VREGOUT pin or to another desired voltage level using an external regulator.

Emergency mode (EMM) and ERR pin (ERR)

7.1

Functional description

The following events trigger the ERRQ pin:

•

Incoming emergency mode signal (EMM) via iso UART interface

Fault input pin ERRQ_ext

The emergency signal is an alternating signal with the frequency f_EMM. In case of an incoming EMM signal, the IC

enters EMM and starts the fault handling.

The EMM signal has a duration of n_EMMperiods. The number of periods the IC needs to detect an EMM signal is

depending on the operation mode:

1.

2.

Idle mode: n_{EMM_dect}

Straight afer wake-up caused by EMM: n_{EMM_dect_wake-up}

The output of the ERRQ pin is open drain. The "low" state is latching and can be reset by the ERRQ_res pin.

The ERR_loc_out pin indicates, whether an incoming EMM signal triggered the error handling procedure. On

detection of an EMM signal, the device sets the ERR_loc_out pin "high" for the duration of t_{ERR_loc_out}. The logic

levels of the pin are VIO and GND.

The ERR_ext_out pin is an output pin. It indicates that the fault was triggered by the ERRQ_ext pin and

represents the deglitched and inverted ERRQ_ext signal. The pin is active high and the logic levels are VIO and

GND.

The ERRQ_ext pin is an input pin to trigger the ERRQ pin externally. The pin is level triggered active low with

a deglitch time of t_{ERRQ_ext_deglitch}. The pin has an internal pull-up resistor R_{ERRQ_ext_PU}to the internal 3.3 V

supply implemented.

The ERRQ_res pin is the input pin to reset the ERRQ pin function. The pin is level triggered active low. The pin

has an internal pull-up resistor R_{ERRQ_res_PU}to the internal 3.3 V supply implemented and includes a deglitch

filter with deglitch time defined by t_{ERRQ_res_deglitch}

.
