Table 4 shows the recommended jumper settings. Table 4. EVM Jumper J 3.4 Description Option Standard IGN When IGN = High (jumper set), the device starts up. Open shuts down the device Set EN This jumper keeps the outputs of the devices active after ignition is turned off (IGN = low). However, a high level on IGN is required for initial start-up. Before initial start-up, the ENOpen allows device shutdown with IGN jumper has no effect. Note that as opposed to IGN, the EN-pin is a logic-level-input, maximum input voltage must not exceed 5.25 V. Set 3.3VPWR This jumper supplies the 3.3-V regulator out of the buck regulator VREG. Set 1.2VPWR This jumper supplies the 1.2-V regulator out of the buck regulator VREG. Set J6 This jumper supplies 1.2-V regulator out of 3.3-V Regulator. Open Test Points Test Points are placed to measure different nodes on the board. Table 5.

Several blocking caps, C4 and C14, are connected from VBAT to GND and help stabilize the supply voltage. For long supply cables, additional bigger caps are helpful. The node PH is the switching node of the buck converter. L1 is the inductor connected to PH and VREG. The diode D1 is the freewheeling diode to allow current flow when the internal High-Side Transistor of the device is turned off. C1 and C2 are the output caps of the VREG regulator. The pin VREG is the feedback line used to close the control loop of the VREG regulator, and is also the supply node for internal use and for the 5-V and 5-VS regulator. The output voltage VREG is available at J1. 3.6 5V (5-V Linear Regulator) 5V is a fixed-regulated output of 5-V ±2% over temperature and input supply using the precision-voltage sense-resistor network. A low-ESR ceramic capacitor is required for loop stabilization; this capacitor must be placed close to the pin of the IC. This output is protected against shorts to ground by a fold-back current limit for safe operating conditions, and by a current limit for limiting in-rush current due to depleted charge on the output capacitance. On initial IGN_EN or EN power cycle the soft-start circuit on this regulator is initiated. The soft-start takes typically 13 ms. This output may require a larger output capacitor to ensure that during load transients the output does NOT drop below the required regulated specifications. 3.7 3.3V Linear-Regulator Controller (3.3-VSENSE) The linear regulator controller requires an external NPN bipolar pass transistor of sufficient gain-stage to support the maximum load current required. The base-drive output current is protected by current-limiting both the source- and sink-drive circuitry. The 3.3VSENSE is the remote sense input of the output of REG3 supply and controls the 3.3VDRIVE output accordingly. This regulator is fixed at 3.3 V with ±2% tolerance using a precision-voltage sense-resistor network. A low-ESR ceramic output capacitor is used for loop compensation of the regulator. A voltage on this pin of less-than approximately 50% of the regulated value initiates a current limit on the 3.3VDRIVE output. This output may require larger output capacitors to support load transients, so the output does not drop below 90% of 3.3 V. 3.8 1.2V Linear-Regulator Controller (1.2-VSENSE) The linear regulator controller requires an external NPN bipolar pass transistor of sufficient gain stage to support the maximum load current required. The 1.2VSENSE is the remote-sense input of the output of 1.2-V supply and controls the 1.2VDRIVE output accordingly. This regulator output is 1.2 V with ±2% tolerance using a precision-voltage sense-resistor network. A low-ESR ceramic-output capacitor is used for loop compensation of the regulator. A voltage on this pin of less-than approximately 50% of the regulated value initiates a current limit on the 1.2VDRIVE output. This output may require larger output capacitors to support load transients, so the output does not drop below 90% of 1.2 V. 3.9 5VS (Protected Sensor-Supply Linear Regulator) 5VS is a fixed-regulated output of 5-V ±2% over temperature and input supply using a precision-voltage sense-resistor network. A low-ESR ceramic capacitor is required for loop stabilization; this capacitor must be placed close to the pin of the IC. This output is protected against shorts to ground by a fold-back current limit for safe operating conditions, and by a current limit for limiting in-rush current due to depleted charge on the output capacitance. This output is also protected against shorts to battery voltage by limiting the reverse current, and because of this, this supply is used to power a sensor outside the electricalcontrol unit, ECU. On initial IGN_EN or EN power cycle the soft-start circuit on this regulator is initiated. The soft-start takes typically 10 ms. This output may require a larger output capacitor to ensure that during load transients the output does not drop below the required regulated specifications.

Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
