Freescale Semiconductor Errata (or Chip Errata) Document Number: MMPF0100ZER Rev. 2.0, 4/2014 MMPF0100Z Errata for Mask 2N47F, 1N18J Introduction Device Revision Identification This errata document applies to mask 2N47F, 1N18J SMARTMOS Products: Table 1. Device Revision Identification Part Number Package MMPF0100NPZES MMPF0100NPAZES 56 Ld 8x8 QFN -WF-Type 56 Ld 8x8 QFN -WF-Type Version Product Marking Die ID PF0100 MMPF0100NPZES 2N47F PF0100A MMPF0100NPAZES 1N18J Device Part Number Prefixes Some device samples are marked with a PM prefix. A PM prefix indicates a prototype device which has undergone basic testing only. After full characterization and qualification, devices will be marked with the MM prefix. General Description This errata document applies to MMPF0100Z series. Table 2. Definitions of Errata Severity Errata Level Meaning High Failure mode that severely inhibits the use of the device for all or a majority of intended applications. Medium Failure mode that might restrict or limit the use of the device for all or a majority of intended applications. Low Unexpected behavior that does not cause significant problems for the intended applications of the device. Enhancement Improvement made to the device due to previously found issues on the design. © Freescale Semiconductor, Inc., 2012 - 2014. All rights reserved. Table 3. Errata for the MMPF0100Z Errata No. Erratum Customer Impact Description When VIN starts, it ramps up from between 100 mV and 400 mV, the regulators may not startup and/or the buck regulator outputs can glitch high momentarily Description: In applications without a valid voltage on the LICELL pin, when VIN starts its ramp from between 100 mV and 400 mV, there can be two failure symptoms: Medium Severity Startup: False start and/or non-start of regulators 1 Fuses may not load during startup for systems with VDDOTP = 0 V (OTP configuration) resulting in non-start of all PF0100 regulators. 2 During VIN ramp up, the top P-MOSFET of buck regulators may turn on while 1.0 V ≤ VIN ≤ 2.1 V. For VIN rise times less than 10 ms, buck regulator outputs can rise up to 1.0 V as VIN transitions from 1.0 V to 2.1 V. For VIN rise times greater than 10 ms, buck regulator outputs can rise up to 2.1 V as VIN transitions from 1.0 V to 2.1 V. Workaround: The workaround consists of external components. Refer to Figure 1. • LDO: 1.3 V to 1.5 V LDO. NCP508 or similar. The LDO should have an enable threshold of 0.9 V or lesser, and a turn on time in the order of 10 s. • Diode: BAS116 or similar. Diode is not required if no coin cell is present at LICELL. Only one 1.0 F is required if no diode if used. Notes: 1. Previously SIP21106, LX8211, MIC5205 or similar LDOs were suggested as workaround. While these will prevent symptom 1) mentioned above, they may not prevent symptom 2) since their enable threshold is above 1.0 V.

Errata for the MMPF0100Z Errata No. Erratum Customer Impact Description No current limit or short circuit protection for VGEN2 at VIN1 < 2.0 V Description: For VIN1 < 2.0 V, current limit of VGEN2 LDO is higher than specification. The interrupt bit does not set in case of a fault. Low Severity VGEN2: VGEN2 current limit not functional at VIN1 < 2.0 V Workaround: VIN1 > 2.0 V ER20 SW1A/B and SW3A/B Regulators: Current sharing is not equal for SW1A/B and SW3A/B in dual phase mode. Fix Plan/Status PF0100 Fixed on PF0100A Output ripple may be higher than Description: specification at load currents The output ripple may be higher than specification at load greater than 1.25 A. currents greater than 1.25 A due to unequal current sharing between the two phases Workaround: Do not use SW1A/B and SW3A/B in the dual phase configuration ER21 RESETBMCU: RESETBMCU fault mode generates a false fault signal when SWBST is used. Applies to: When SWBST is used without load in the AUTO mode, RESETBMCU may go low and trigger a false fault. Applies to: Fix Plan/Status PF0100, PF0100A No fix scheduled Description: When RESETBMCU is in fault mode (OTP_PG_EN bit = 1) and SWBST operates at light loads in AUTO mode, the SWBST inductor current may be limited by internal circuitry resulting in a false RESETBMCU signal. The erratum does not apply if SWBST is not used. ER22 Workaround: There are two workarounds for this erratum. 1 Do not turn on SWBST in the OTP sequence. Change operating mode of SWBST to APS before turning it on via software. 2 Replace the 2.2 H inductor with a 4.7 H on SWBST.
