What are the key features of ADS1202IPWTG4?

  • Delta-sigma current shunt modulator architecture delivers high-resolution, isolated current measurement for 3-phase BLDC motor drives
  • 8-pin TSSOP package with 0.25 mm pitch enables compact placement in space-constrained motor controller PCBs
  • Peak reflow temperature rating of 260°C and RoHS-compliant construction (JESD-609 e4) for standard SMT assembly processes

What is ADS1202IPWTG4 used for?

ADS1202IPWTG4 is used as a current sensing front-end in 3-phase brushless DC motor controllers, variable frequency drives, and servo amplifiers where precise phase current measurement is required for FOC (field-oriented control) algorithms. Its delta-sigma modulator output connects directly to digital isolators or isolation-compatible digital filter ICs, enabling safe galvanic isolation between high-voltage motor phases and control logic. The device also suits power converter current sense loops in solar inverters and UPS systems.

Frequently Asked Questions

What modulator architecture does ADS1202IPWTG4 use, and how does it support isolated current measurement?

ADS1202IPWTG4 uses a delta-sigma modulation architecture that converts the shunt resistor voltage to a high-speed 1-bit bitstream output. This bitstream can cross a digital isolator (such as a capacitive or optical coupler) without analog signal integrity loss, enabling galvanic isolation between the high-voltage motor phase and the low-voltage MCU. The modulator output is then filtered digitally by a SINC filter to recover a multi-bit current sample, typically at 10 MHz clock with 12-bit effective resolution.

Which motor control topologies are best matched to ADS1202IPWTG4 current sensing?

ADS1202IPWTG4 is optimized for 3-phase brushless DC (BLDC) and AC induction motor drives using shunt resistors in each phase leg for current measurement. Field-oriented control (FOC) algorithms require phase current samples at every PWM cycle, and the ADS1202 modulator's continuous bitstream output supports oversampling rates up to several megahertz, enabling sampling latency below 1 µs per phase at typical 10 kHz to 20 kHz PWM frequencies.

What is the package size of ADS1202IPWTG4, and how does it compare to SOIC-8?

ADS1202IPWTG4 is housed in an 8-pin TSSOP package with a pin pitch of 0.25 mm and a body width of approximately 3 mm, making it significantly smaller than a standard SOIC-8 with 1.27 mm pitch. This smaller footprint saves approximately 60% of PCB area per device, which is critical in motor drive gate driver boards where multiple current sense channels must be routed within a limited layout area.

Is ADS1202IPWTG4 still in active production, and what should buyers consider for long-term supply?

ADS1202IPWTG4 shows a YTEOL of 0, indicating it is at or near end of its estimated product lifecycle with Texas Instruments. Buyers should consult TI's product change notices and evaluate pin-compatible active alternatives such as ADS1205 or ADS1207 for new designs. For existing production requiring ADS1202IPWTG4, stocking at least 12 to 24 months of inventory is recommended to mitigate supply risk.
