1 / 25 page S-19190 Series www.sii-ic.com FOR AUTOMOTIVE 105°C OPERATION VOLTAGE MONITORING IC WITH CELL BALANCING FUNCTION © SII Semiconductor Corporation, 2015-2017 Rev.1.5_00 1 The S-19190 Series is a voltage monitoring IC with a cell balancing function and includes a high-accuracy voltage detection circuit and a delay circuit. The S-19190 Series is suitable for cell balancing and overcharge protection of batteries and capacitors. Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the purpose, contact to SII Semiconductor Corporation is indispensable. Features • High-accuracy voltage detection circuit Cell balancing detection voltage: 2.0 V to 4.6 V (5 mV step) Accuracy ±12 mV (2.0 V ≤ VBU < 2.4 V) Accuracy ±0.5% (2.4 V ≤ VBU ≤ 4.6 V) Cell balancing release voltage: 2.0 V to 4.6 V *1 Accuracy ±24 mV (2.0 V ≤ VBL < 2.4 V) Accuracy ±1.0% (2.4 V ≤ VBL ≤ 4.6 V) Overcharge detection voltage: 2.0 V to 4.6 V (5 mV step) Accuracy ±12 mV (2.0 V ≤ VCU < 2.4 V) Accuracy ±0.5% (2.4 V ≤ VCU ≤ 4.6 V) Overcharge release voltage: 2.0 V to 4.6 V *2 Accuracy ±24 mV (2.0 V ≤ VCL < 2.4 V) Accuracy ±1.0% (2.4 V ≤ VCL ≤ 4.6 V) • Built-in Nch transistor with ON resistance of 5 Ω typ. between the CB pin and the VSS pin • Current consumption: 2.0 μA max. (Ta = +25°C) • Delay times are generated only by an internal circuit (External capacitors are unnecessary). • CO pin output form and output logic are selectable: CMOS output Active "H", active "L" Nch open-drain output Active "H", active "L" • Switchable to power-saving mode by using the CE _____ pin • Operation temperature range: Ta = −40°C to +105°C • Lead-free (Sn 100%), halogen-free • AEC-Q100 qualified *3 *1. Cell balancing release voltage = Cell balancing detection voltage − Cell balancing hysteresis voltage (Cell balancing hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.7 V in 50 mV step.) *2. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage (Overcharge hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.7 V in 50 mV step.) *3.
