Holt Integrated Circuits

Programmable over Serial Peripheral Interface (SPI). Accurate Load Current Sensing with built-in ADC.

16−Channel Low-side driver

The HI-84216 is a smart 16-channel low-side driver designed for high-reliability applications. The device uses a Serial Peripheral Interface (SPI) for intelligent switch control, monitoring and advanced diagnostics.

The HI-84216 is capable of sinking 250mA per channel with up to 4A total sink current for parallel channel operation. An 8-bit ADC provides accurate measurement of channel current and temperature while an internal PWM clock generator with 16-bit resolution provides application flexibility.

Key Features:

  • Compact 16-channel low-side driver (6mm x 6mm)
  • 250mA sink current per channel
  • Sink up to 4A when all channels used in parallel
  • Accurate current/temperature measurement
  • Access diagnostics and program via 10 MHz SPI
  • 0.5 Ω On-Resistance per channel
  • < 1μA leakage current with low quiescent power
  • Digital I/O powered with 1.8V to 5.0V
  • Continuous Online Built-in Self-Test
  • Host-controlled output enable pin
  • Operating Temperature:
    -40°C to +85°C or -55°C to +125°C
  • Over-current shutdown protection with programmable retries
  • Thermal fail-safe
  • Internal or external PWM option for soft-start or LED dimming
  • Internal programmable PWM clock generator with 16-bit resolution on pulse width and period
  • PWM configured on a per-channel basis over SPI
  • PWM clock fault detection
  • Optional programmable watchdog timer
  • Programmable High/Low Current Thresholds
  • Open/Short Load Detection
