S-19721 Series Automotive Voltage Tracker with Anomaly Notifications

ABLIC’s voltage tracker is ideal for automotive applications including engine and transmission-related devices

Image of ABLIC S-19721 Series Automotive Voltage Tracker with Anomaly NotificationsABLIC's S-19721 is a voltage tracker with one of the industry's lowest class offset voltages of ±4.5 mV. The low offset voltage contributes to a low permissible error in voltage tracking, improving the sensor reading accuracy of various sensors.

The S-19721 has an anomaly notification that detects its abnormal activity and outputs it's status. It can handle three types of abnormalities: overvoltage, overcurrent at the output pin, and heating of itself. It is possible to select the appropriate combination of outputs according to the specifications and applications.

Features
  • Input voltage: 4.0 V to 36.0 V
  • Output voltage: adjustable down to 2.0 V min.
  • Offset voltage: ±4.5 mV (0.1 mA ≤ IOUT ≤ 250 mA)
  • Dropout voltage: 330 mV typ. (VADJ = 4.0 V, IOUT = 125 mA)
  • Current consumption:
    • During operation: 40 μA typ.
    • During power-off: 3.7 μA typ.
  • Output current: possible to output 250 mA (VIN = VADJ + 2.0 V) (Please make sure that the loss of the IC will not exceed the power dissipation when the output current is large)
  • Input capacitor: a ceramic capacitor can be used (4.7 μF or more)
  • Output capacitor: a ceramic capacitor can be used (4.7 μF to 1,000 μF)
  • Built-in overcurrent protection circuit: limits overcurrent of output transistor
  • Built-in thermal shutdown circuit: detection temperature +175°C typ.
  • Built-in overvoltage detection circuit: A/B type: detects an output short-circuit of the higher voltage
  • Reverse current protection function: IREV = -5 μA min. (VIN = 0 V, VADJ = 5.0 V, VOUT = 16.0 V)
  • Anomaly notification function
    • INT pin notifies operation anomaly of the IC
    • A type: overvoltage, ground fault, overheat
    • B type: overvoltage, overheat
    • C type: ground fault, overheat
  • Operation temperature range: -40°C to +125°C
  • Lead-free (Sn 100%), halogen-free
  • Withstand 45 V load dump
  • AEC-Q100 qualified (Contact ABLIC sales representatives for details)
  • Package
    • TO-252-9S
    • HSOP-8A
    • HSNT-8 (2030)
Applications
  • Power supplies for automotive ECU off-board ratiometric sensors
  • For automotive use (engine, transmission, suspension, ABS, related devices for EV/HEV/PHEV, and others)
