6.2 ESD Ratings
V_(ESD)
Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001 ⁽¹⁾
Electrostatic discharge _{Charged-device model (CDM), per JEDEC specification JESD22-C101 (2)}
VALUE
±6000
±750
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

(1) Operational at VREF = 0 to 0.3 V, but accuracy is degraded
(2) The voltages applied to the inputs should have at least 800 ns of pulse width to ensure detection. Typical devices require at least
400 ns. If the PWM frequency is 200 kHz, the usable duty cycle range is 16% to 84%.
(3) Power dissipation and thermal limits must be observed
